1.5 4KXL PAR- PAR will not utilize "lone" OFFSET constraints
Record #4194
Product Family: Software
Product Line: FPGA Implementation
Product Part: par
Problem Title:
1.5 4KXL PAR- PAR will not utilize "lone" OFFSET constraints
Problem Description:
Urgency: Standard
General Description: If the only constraints in a .ucf or .pcf are "TIMEGRP OFFSET" (no PERIOD, FROM
TO, etc...) PAR doesn't invoke timing-driven operation. If the .ucf or .pcf contains a PERIOD, FRO
M TO, etc... the OFFSETs are then reported at the timing summary given at the end of the PAR job. TR
CE always reports correctly, so this behavior seems to be unique to PAR.
Solution 1:
This is only related to PAR. TRCE works correctly.
This problem was fixed in the 1.5i release.
