intel_rtile_cxl_top_cxltyp3_ed with out of order support (ooo enabled) Timing issues (23.2) - intel_rtile_cxl_top_cxltyp3_ed with out of order support (ooo enabled) Timing issues (23.2) In building the intel_rtile_cxl_top_cxltyp3_ed with the ooo enabled we get some design assistant failures around the timing, of concern are these: TMC-20023 - Invalid Set Net Delay Assignment TMC-20025 - Ignored or Overridden Constraints TMC-20026 - Empty Collection Due To Unmatched Filter Are there any updates to the constraints for this design? Replies: Re: intel_rtile_cxl_top_cxltyp3_ed with out of order support (ooo enabled) Timing issues (23.2) I have checked with the internal team. These DRC messages are expected. The engineering team is still working on cleaning up the sdc constraints in 23.3. The DRC violations should not impact timing, and not cause any functionality problem. Replies: Re: intel_rtile_cxl_top_cxltyp3_ed with out of order support (ooo enabled) Timing issues (23.2) Thanks for the elaboration. Let me check and get back to you. Replies: Re: intel_rtile_cxl_top_cxltyp3_ed with out of order support (ooo enabled) Timing issues (23.2) Hi @JonWay_C_Intel , Not worried about the DRC checks, it's the 700+ timing constraints from the various *.sdc files that aren't being used that I have issue with. They are below the DRC checks you mention that have been around for a while, the ones below (#7-9): TMC-20023 - Invalid Set Net Delay Assignment TMC-20025 - Ignored or Overridden Constraints TMC-20026 - Empty Collection Due To Unmatched Filter Are the new ones that are concerning. Replies: Re: intel_rtile_cxl_top_cxltyp3_ed with out of order support (ooo enabled) Timing issues (23.2) Hi @brian1211 Is this related to https://community.intel.com/t5/FPGA-Intellectual-Property/CXL-type-3-design-example-Design-Assistant-Errors/m-p/1502466#M27791 These DRC Checks were enabled late in 22.4 onwards. These errors are expected for 23.1 and expected to be fixed by 23.3. DRC violations are not impacting the functionality so far.
