3.1i XST - XST creates an .edn file with lines that are longer than NGDBuild can process.


Keywords: XST, synthesis, EDN, .edn, netlist, NGDBuild

Urgency: Hot

General Description:
XST generates a netlist with lines longer than 256 characters by creating a signal name with a repetitive string appended to it.

For example:


This causes NGDBuild to report the following error.

ERROR:NgdBuild:195 - Identifier found on or above line 2066 in file V3200E.edn, exceeds the 255-character limit imposed by the EDIF specification. Please contact the vendor that created this EDIF file.


The only known work-around is to name the components/modules or nets in such a way as to not run into this problem.

NOTE: This problem is resolved in the 4.1i software release.
