4.1i ABEL - "Internal Error 0001: line 282 in file "../s/net_util.c"..."

Description

Keywords: Foundation, internal error, AHDL2BLF, ABEL

Urgency: Standard

General Description:
When I compile an ABEL design, a message reports: "Errors Found."

The abl2edif.log file (or console window if ISE is used) contains the following error message:

"AHDL2BLF ABEL-HDL 7.20 Compiler, Build D.21
iSE Release 1.00 Copyright (c) 1999 Xilinx, Inc. All rights reserved.
Internal Error 0001: line 282 in file "../s/net_util.c"
Attempt to add node with same name as some existing node. ABL2EDIF has failed."

Solution

Check the declarations section to ensure that a NODE or SIGNAL has not been declared twice. (This is most common in bus declaration.)

In the following example, b4 and b3 are declared twice, which causes the above error:

b4..b0 pin istype 'reg';
b7..b3 pin istype 'reg';
