Problem Title:
map 1.5iS2/4062xl: FATAL_ERROR:baste:bastecmpin.c:314:1.27.18.2 - NULL pinhook
Problem Description:
A case has been seen that fails with the map error:
FATAL_ERROR:baste:bastecmpin.c:314:1.27.18.2 - NULL pinhook detected for pin 11
on comp BER/BER_ANALYSIS/INPUT_CONTROL/CLOCK_CONTROL/$1I178/$1N20. Process
will terminate. Please call Xilinx support.
Solution 1:
This error is known to occur when flops that are chained together (one drives the other) are packed
into the same CLB. The error can be avoided by assigning a unique BLKNM attribute to each flop in th
e chain which ensures that they are all packed into different CLBs. BLKNM attributes can be assigned
to flop instances using the .ucf file:
INST "flop_name" BLKNM=XYZ ;
The problem is fixed in version 2.1i which is set to begin shipping in late June.
