Problem Title:
NGDANNO 1.5: FATAL_ERROR:basut:basutblist.c:348:1.2-Maximum iterator count exceeded
Problem Description:
Urgency: Standard
General Description: When running ngdanno with the following
command line:
ngdanno -p <name>.pcf <name>.ncd <name>.ngm
the following error may be observed:
FATAL_ERROR:basut:basutblist.c:348:1.2 - Maximimum iterator
count exceeded. Please call Xilinx support.
Solution 1:
The workaround is to run ngdanno without using the .pcf file if it is
not needed. as stated below:
From Dynatext->Developement System Reference Guide->
Chapter 15 NGDAnno-> NGDAnno options->
-p (PCF File)
-p pcf_file.pcf
The -p option allows you to specify a PCF (Physical Constraints) file
as input to NGDAnno. You only need to specify a constraints file if it
contains the following:
--Level information (CMOS or TTL) for IOBs in a 4000E or 4000EX design
--Prorating constraints
Prorating constraints and prorated delays are described in the
"OFFSET Timing Specifications" section of the "Using Timing Constraints"
chapter.
