Table 9-10.Customer-reported Defects and Enhancement Requests with Case Numbers
Case Number | Summary | Resolution
--- | --- | ---
00910093 | MPF Programming issue with Zeroize and Authentication `PROC_ENABLE`. | `ENC_DATA_AUTHENTICATION`, `ZEROIZE_LIKE_NEW`, and `ZEROIZE_UNRECOVERABLE` actions now pass for exported bitstream file/FlashPro Express job when include plaintext passkey is checked and these actions are disabled in the Configure Security tool.
122358 | If the PolarFire CCC is configured in Post-Divider Feedback Mode, the phase shift continuously changes after power cycling the device (Core Version 2.2.100). | For information, see section PLL Phase Alignment when Using Post-Divider or External Feedback Mode.
00998202 | The `vdir` command used with ModelSim ME Pro 2021.3 for pre-compiled libraries delivers the incorrect result of unknown version. | This issue is resolved with the ModelSim ME Pro provided with Libero v2022.2.
493642-2872943656, 493642-2880122269, 00850681 | RTG4_CCC: Simulation of RTG4 Design using a FCCC PLL with external feedback: phase delay is not adjusted. | For information, see section Added Simulation Support for RTG4 PLL Feedback Delay.
00967580 | RTG4_ODT: Dynamic ODT macro simulation library bug. | The `ODT_DYNAMIC` simulation model has been updated to match the port names with libero generated files.
— | A deadlock condition with the RTG4FCCCECALIB core occurred when configured for external feedback mode and output option-1 to hold the outputs LOW until the lock asserts. | If External Feedback is selected and the FB_CLK source is one of the CCC's GLx outputs, your CCC output setting of Hold outputs LOW until PLL locks is ignored for the GLx that is sourcing the `FB_CLK` and that GLx is allowed to operate prior to lock assertion.
— | When setting permanently write protect fabric in Configure Permanent Locks tool, the exported bitstream file/job will also program sNVM update protection to be locked for update (i.e., protected by Flashlock/UPK1) even though sNVM updates were allowed without Flashlock/UPK1 in Configure Security tool. | Security settings for Fabric and sNVM can now be saved or read separately.
— | Installing Libero SoC v2022.1 on a Personal Computer (PC) running windows causes the PC to restart unexpectedly without providing a notification message. | To avoid this issue, install Visual C++ Redistributable 2015-2022 x86 on the PC before installing Libero SoC v2022.1.
01037234 | Stage3 Initialization Client data of the Golden and Update images is not available in the exported SPI Flash image. | The Export SPI Flash Image tool now exports data for STAGE3 initialization client imported via SPI Bitstream client in the SPI-Flash tab of the Configure Design Initialization Data and Memory tool.
912639 | HDL_LANGUAGE: VHDL: Libero is not parsing files correctly to pass to Synthesis. | Libero is not parsing the dependent package files correctly to pass to Synthesis.
967427 | G4: Sanitize option is increasing stpl file size unexpectedly. | Generate Bitstream, Export Bitstream, and Export FlashPro Express Job tools do not unnecessarily include entire fabric data when sanitizing eNVM as part of an ERASE action.
493642-2092580450, 493642-2707760243 | Add information for `update_and_run_tool` in the Libero online help. | A tool state can be Out of Date (OOD) for various reasons, such as when there is a change in the source files, a change in settings, a parent tool state cleaned, or out-of-date. If a tool is out of date, the `update_and_run_tool` Tcl command considers the updated source files and settings and runs all of its parent tools if they are cleaned or out of date, and then runs the specified tool itself.
493642-2868126969 | COMPONENT_MANIFEST: Include SDC in manifest text files of SmartDesign generated Core IPs. | For information, see section Constraint Files in the Manifest Text Files of Generated Core IPs.

00938240, 00972272 | If reserve pins for probes is unselected, System Controller suspend mode is unavailable. | When configuring programming options, the Disable probe read/write option depends on a Constraints Manager option that reserves pins for the probe. If the reserve pins for probe option are not selected, probe read/write must be disabled and cannot be changed. Default for the disable probe read/write is based on the current reserve pins for probe setting: off and available for you to change if pins reserved or on and unchangeable if pins are not reserved.
939458 | Add a popup when discrete clock is selected in the Programmer Settings dialog. | In addition to adding a pop-up warning in the Programmer Settings dialog, a warning is added when you perform a Program, Verify, Erase, or Authenticate action to advise you about significant programming time increase in case the discrete clock mode is set for the selected programmer

968882 | Repair min delay affects max timing closure. | Automatically generated clock jitter does not impact min-delay timing.
878534 | STPS-373 - SmartTime in v2021.2 considers invalid false path constraint. | Applied false path constraints now work properly and warnings about invalid false path constraints no longer appear.
904319 | STPS-381 - Constraint Editor GUI column width issue in Libero v2021.2 and v2021.3. | The constraint browser pane on the left side can now be reduced and increased without issues or standard column width.

— | For PolarFire SoC Libero designs that contain eNVM, running VERIFY_DIGEST after programming device fails with the message eNVM digest verification: FAIL. | The eNVM client in Configure Design Initialization Data and Memories tool has a new option to include pages for digest calculation, which resolves this issue.
