XABEL, Foundation F1.x: Internal Error 18911 in Blif2net (abl2edif)

Description

Keywords: abel, keep, blif2net, abl2edif

Urgency: Standard

General Description:

The following error occurs during the blif2net program in
ABEL synthesis:

Internal Error 18911: Unable to find combinatorial gate
associated with <node_name>.

where <node_name> is a node with the "istype 'keep'" attribute.

解决方案

1

This is due to a bug in the Blif2net program, which is the
EDIF writer for XABEL. A possible workaround for CPLD
top-level Abel designs is to use the "Plusasm" flow, which will
write out a PLD instead of an EDIF file. Please see
(Xilinx Solution 2776) for more information on enabling this
flow.

A workaround for this problem is to replace the
c:\xilinx\bin\nt\lib5\epld_dev.fft file with the one on the web
site at
