Simscope Release History

How to upgrade?

Note: to upgrade your Simscope or Tunnel version, please follow the Upgrade instructions.

1.536

1. `feature` Dark Mode Theme

Simscope now has a Dark mode, for users who have enabled in the browser/operating system, or users who prefer rendering in dark colors.

Dark/Light mode can be toggled manually via the icon in the top-right corner.

2. `bugfix` Fixed signature bucketing bug with assertions

Some UVM assertion errors were begin over-collapsed. This has now been fixed so that each assertion name will be a separate signature.

[sigs]

# Latest signature bucketizer, with customizable hierarchy
bucketizer = "v2"

3. `bugfix` Run Back/Next link filters with same component

The Previous/Next links when navigating regressions now follow the current component.

4. `bugfix` Event log heartbeat

The event log now has a heartbeat, to keep connections open even if no activity.

5. `feature` Renamed Metrics to Dashboards

To make it clearer, the header now is called Dashboards.

1.535

1. `feature` Event Log

For administrators, there is now a live Event Log, which allows watching and debugging log events dynamically from the browser.

This allows improved debugging of JSON job and regression messages, and allows simpler watching of warnings and errors.

For example, you can watch for a regression release/124, and only those events will be shown.

2. `feature` Changed Project view to 7 days

The default Project view now shows 7 days, instead of 30.

3. `bugfix` Run tag drilldown fixed

When clicking on Run Tags, this now filters based on:

Current filters.
Plus the new run tag clicked.

Previously, this would apply the run tag, but remove all other filters.

4. `feature` Added Priority field for Coverage

Coverage now allows a priority field. This is used in the testplan parsing template.

5. `bugfix` Empty heatmap fixed

Heatmap charts with empty (null) data now render as blank charts, instead of showing a no data metched error message.

1.534

`feature` Testplan/Coverage updates

Various bug fixes for the Testplan flow:

Added Balanced score mode, where each coverage group is averaged with the same weight.
Fixed a testplan parse bug where Feature was rendering as blank.
simscope-gsheets-testplan.py: added --runtag option, to allow filtering regressions by Run Tag

1.533

1. `feature` New Simscope Logging

Simscope now automatically runs with a file-based message logging file called simscope.log, stored into the DB directory.

Also, by default, console-level (e.g. stdout) logging has been reduced to show warnings and errors only.

There is also a web-based log watching algorithm too.

For more verbosity, you can enable enable DEBUG level logging, by setting the environment variable:

$VEROPS_LOG_LEVEL=debug

2. `feature` Improvements to Testplan parser

The Testplan Parser now supports:

Hierarchical Feature / SubFeature
Gating depending on the Priority and Status fields

3. `bugfix` u64 job metadata fixed

There were several comparison bugs in hex (ie uint64) job metadata that have been fixed, including bit slicing operations (e.g. my_var[63:61] == 0x2).

4. `bugfix` Fixed wide source code bug

The job details page now wraps better when rendering long (wide) source_code fields.

5. `bugfix` Increased dashboard chart limit

Metric dashboards have been increased to allow up to 36 charts (previously 18).

1.532

`bugfix` Job config field wrapping

Fixed SIMSCOPE-155: job config field was overflowing incorrectly.

`bugfix` Gantt chart click

Users can now click anywhere on the gantt chart to drill into job details.

1.531

1. `bugfix` Increase Gantt chart limit to 5000 jobs

The Regression Gantt page has been increased to render up to 5000 jobs on a single chart.

2. `bugfix` Gantt bar hyperlinks

Clicking on Gantt bars (or row) now opens the job.

Project cookie were confusing, so they have been disabled again.

When clicking on the Projects tab, it always goes to the project selector, instead of going to the previous project page.

4. `feature` Compute time auto-scale

Compute times now auto-scale their time units, to represent smaller time duration values. Previously they always rendered in "day" scale.

Examples:

10.2 m instead of 0.0 d
1.5 hr instead of 0.1 d

5. `feature` Coverage DB siblings

Regressions containing multiple coverage DB's now have links to sibling DB's.

1.530

1. `bugfix` Fixed Regression grouping/drilldown

When viewing Grouped Regressions, the list will now properly limit to a single page of results.

For example, if page size is 200, the resulting page will show up to 200 unique grouped resuls.

Grouping modes:

Group-by component
Group-by run group
Group-by regression series name

2. `bugfix` Fixed grouping regex drilldown

When drilling down in grouped regression mode, the Regex selection is kept.

There was a bug in previous releases, where this field would be cleared during drilldown.

3. `bugfix` Fixed Gantt chart sorting

Gantt charts now sort more intuitively;

Ascending sort: sort based on job-start timestamps
Descending sort: sort based on job-finish timestamps

4. `bugfix` Fixed coverage merge to allow entire page of results to be merged

SIMSCOPE-154

In previous releases, Coverage Merge was limited to 50-model merge maximum.

Now, it is limited to the page size selection.

For example, if you have a 200-model page, you can merge 200 models simultaneously.

1.529

1. `feature` Subproject within Regression JSON

Regression JSON can now optionally contain a subproject field, to allow automatic populating of component subproject when a run is started.

If the field is blank (or omitted), subproject is left unchanged.

2. `feature` Added Score Meter in Projects

The Project details page now includes a Score Meter display of each component.

The Project section now includes a cookie to save and restore the previous search configuration.

4. `bugfix` Signature title search in Triage Report

Filtering the Triage Report by Signature title was broken in previous releases.

This is now fixed.

1.528

1. `feature` Added support for uniqueid Live publishing

This release adds a simpler Live job matching algorithm based on uniqueid job field.

2. `feature` Chart: added Group By: Run Group

Charts can now be grouped by Run Group.

3. `bugfix` Fixed incorrect Score calculation of Aborted regression results

In previous releases, regressions with missing/lost jobs may show an incorrect Score (e.g. 100%), even if the regression contained lost jobs.

Now the score automatically includes aborted/lost jobs.

4. `bugfix` Fixed Project Component view with empty components

If Components have no matching jobs inside the Projects page, they now show up grouped under an Empty sub-group, to clarify why they show up as faded out.

5. `feature` Added Chart configuration: seriesstrippatterns

SIMSCOPE-141

Charts now have an optional configuration seriesstrippatterns, which is a list of optional regular expressions, allowing shortening of long series names, when rendering charts.

For example, if you have a long regression called my/super/long/regression/daily/snake/202, you can add this to your simscope.config to remove the long prefix:

[chart]
# Strip series patterns when rendering charts (regular expressions).
# Example: strip pattern: [my ... daily/]
seriesstrippatterns = "^my.*daily/"
# Also strip 'projectA' (anywhere)
seriesstrippatterns = "projectA"

6. `bugfix` Fixed a regex Build filter bug

Fixed a bug in regression search where regex field was not propagating when drilling into regression details links.

7. `feature` Upgraded compile toolchain

This release updates the compile toolchain, requring a minimum Linux OS, equivalent to RedHat7 or higher.

1.527

1. `bugfix` Regression grouped view pagination fix

In previous releases, when grouping regressions by Component, Series, etc., the summary view could paginate to a single page, containing the first matching 50 regressions incorrectly.

This resulted in an invalid summary view that was missing records.

This bug is now fixed, so that the summary page should summarize based on 1000 records.

2. `bugfix` Fixed double-metrics-reindex bug

In previous releases, reindex could be scheduled simultaneously in parallel.

1.526

`feature` Added merge for formal coverage

Formal coverage DB's can now be merged together.

Note: identical property names are combined as siblings, rather than merged into a single property.

1.525

1. `feature` GUI simscope.config editor

The simscope.config can now be edited and saved to disk from within the Simscope GUI, to allow easier configuration changes without needing a terminal.

2. `feature` Metrics DB incremental updates

The Metrics DB now supports incremental updates, upon a regression finishing (or timing out).

Charts should now be fresh for all non-live regressions.

Note: this requires a one-time table reindex after installing this release:

Click Admin Lock → Repopulate Metrics Table
be patient: this could take a few hours

3. `bugfix` Chart wide-legend-table

The legend table now automatically shrinks to adjust to the size of the series names in the chart.

In previous releases, this used a fixed width, which could be too wide if there were short series names.

1.524

`feature` New Projects tab

This release contains a new Projects tab, to allow simplified drilldown navigation:

Project → Component → Regression.

1.523

1. `feature` Triage percentage collapse algorithm

The Triage calculation has been changed, so that if a signature has been split into:

NEW + ASSIGNED

Then the triage percentage will merge {NEW+ASSIGNED} together (instead of having separate counts).

This results in a slightly higher Triage % score.

Note: when calculating the Assignment %, NEW and ASSIGNED counts are both used separately. So the score is the same as previous versions.

2. `bugfix` 100% charts

Line Charts with a fixed 100% value now render with 100% values at the top of the chart instead of the middle.

3. `bugfix` Blank charts

Charts with empty datasets now render as a blank/empty chart, instead of showing an error message.

4. `feature` SMTP CA Certificates

Added SMTP CA Certificates configuration option, to allow custom X.509 certificates.

1.522

`feature` Regression plugins can now be dynamic

Regression plugins can now be dynamic, so you can save a search that only matches the latest run in a branch/component/etc.

Then when the next regression matching arrives, the plugin will execute against it instead.

1.521

1. `feature`Regression search by Updated timestamp

Regressions can now be searched by dates using the Update timestamp.

This allows finding regressions which were run a while ago, but have been updated with coverage or metadata values.

2. `feature` LDAP dndisablepattern

Added dndisablepattern to the LDAP configuration to allow user disabling based on their DN (Designated Name) value.

This feature enables automatically disabling users in Simscope (and free up license seats).

Example:

[ldap]
# Optional: DN Disable Pattern: If your organization disables LDAP users by changing their DN
#           (Designated Name), this variable allows a regular expression to auto-disable a user.
# Note: this requires 'directoryrefresh' to trigger.
#
# Here is an example where users get moved into the OU (Organizational Unit) called Disabled Users:
dndisablepattern = "OU=Disabled Users"

# Refresh the user directory every 24 hours
directoryrefresh = "24h"

perf_reg_int = 0b1101

4. `feature` New bitwise job metadata slicing

SIMSCOPE-80

Integer-based job metadata fields can now be bitwise indexed (for Rules or searches).

Example:

my_csr01[6:1] < 0x1a

This slices the my_csr01 metadata fields on the bits 6..1 and compares against hex value 0x1a

This expression would be equivalent to shifting my_csr01 by one bit and AND-ing the result with `0b

5. `feature` Added automatic DB integrity check

This now runs an hourly integrity check, and will pause RabbitMQ if the integrity check fails.

To disable the integrity check (not recommended):

[server]
# Skip automatic integrity check (NOT RECOMMENDED)
# skipintegritycheck = true
