Problem Title:
XEPLD 6.0: hi604: [Warning] Unexpected TIMESPEC string ignored


Problem Description:
Keywords: xemake6, hi604, constraints, xact-performance

Urgency: Standard

General Description:

Upon invoking "xepld" on a 9500 part, the following may be encountered if you ha
ve TIMESPECS in the design or in a constraints file:

hi604:[Warning]Unexpected TIMESPEC string FROM:PADS(PTOHP):TO:FFS=8.0, Ignored.
  Note that XC7000 devices support FROM:TO syntax and do not
  support the old-style P2P, C2S timing specifications.

The TIMESPEC is valid, and the signal "PTOHP" does indeed exist in the .xnf file
.



Solution 1:

The problem is that XEPLD calls a subprogram "xemake6", and this program has a b
ug. It will not accept any TIMESPEC string that references a signal with the str
ing "TO" in it. Therefore, the signal "PTOHP" will need to be renamed to somethi
ng else, such as "P2HP".
