Description

Keywords: basrtalg.c, basrtalg. 148, vccgnd_splitnet(), PWR, VCC,
GND, hard macro, nmc

Urgency: Hot

General Description:
PWR/GND routing changes in 3.1i Service Pack 4 have broken
the PWR/GND routing for Hard Macros (.nmc) that have PWR/GND
connections. The router fails with the message:

FATAL_ERROR:Route:basrtalg.c:148:1.8.2.2 - deposit:vccgnd_splitnet()
failed for signal:GLOBAL_LOGIC0 Process will terminate.

Solution

1

This problem is fixed in the latest 3.1i Service Pack available at:
http://support.xilinx.com/support/techsup/sw_updates. The first
service pack containing the fix was 3.1i Service Pack 5.

A workaround is to set the following environment
variable before running PAR:

set VCCGND_OFF=1 (PCs)
setenv VCCGND_OFF 1 (WorkStations)
