Table 5-4.Customer-reported Defects and Enhancement Requests (No Case Numbers)
Summary | Resolution
--- | ---
Users cannot export a component description Tcl script for SmartDesign Testbench. | Added support for SmartDesign Testbench to export a component description Tcl script.
SmartDesign loses loopback connectivity of the instance when updating the instance port list. | This issue has been resolved: Instance loopback connections are now preserved when an instance port list changes.
Bus slices are lost when a new slice is created that overlaps existing ones. | This issue has been resolved: Bus slices are now preserved when creating a new slice with an overlapping range.
Jitter reports should state that values are peak-to-peak. | Added a statement in the report header that values are peak-to-peak.
PolarFire IBIS Transceiver Reference clock models are not supported. | PolarFire IBIS Transceiver Reference clock models are now supported.
The tool crashes when checking constraints when a master clock is invalid. | Added a check to prevent such crashes.
