M1.4: TIMESPEC paths originating from .NMC macros (physical macros) do not get written by Map to the .PCF file
説明
Keywords: 100684, nmc, macro, physical macro, hard macro, pcf
Urgency: standard
General Description: In all versions of Map up to and including vM1.4, TIMESPEC paths originating from .NMC macros (physical macros) do not get written by Map to the .PCF file. As a result, TIMESPECs in a design that begin in a physical macro do not get read by PAR.
ソリューション
Edit a copy of the .pcf file generated by Map and manually add the .NMC-originated TIMESPEC(s) to the .PCF file after the "schematic end" line. Then, when running PAR, specify the name of the PCF file copy that you have edited as one of the inputs to PAR:
par inputdesign outputname pcfile
Use NCDREAD to determine the physical name of the block or net referenced in the TIMESPEC (see the Chapter 1 of the Development System Reference Guide for instructions on using NCDREAD, and Chapter 8 of the same document for details on the .PCF file format).
