3.1i Hitop - "Warning: hi429 - Cannot apply TIMESPEC..." occurs on what seems to be a valid signal

Description

Keywords: Constraints Editor, Hitop, TIMESPEC, valid, signal, error, hi249

Urgency: Standard

General Description:
HITOP issues a warning similar to the following:

WARNING:hi429 - Cannot apply TIMESPEC TS_ADDR_TO_A1_CS =
MAXDELAY:FROM:ADDR:TO:A1_CS:10.000000 nS because of one of the following:
(a) a signal name was not found; (b) a signal was removed or renamed due to optimization;
(c) there is no path between the FROM node and TO node in the TIMESPEC.

Solution

This error message may appear if you are using a TNM_NET to place a timing name instead of TNM.

The following example will work:
NET clk TNM = myclk ;

The following example will not work:
NET clk TNM_NET = myclk ;

This is fixed in the 4.1i software release.
