FPGA Express produces XNF with lines greater than 2048 characters, ERROR:basxn:53 - Line number 30788: maximum field length exceeded

説明

Keywords: XNF, Express, Foundation, TIMESPEC, 2048, basxn:53, timing

Urgency: Standard

General Description:
With FPGA Express 3.1 and earlier, when one writes out timing constraints, they are placed in
the XNF file. If the timing specification becomes complex enough, these lines become exceedingly
long and may violate the 2048 character limit. The following error will result during implementation:

ERROR:basxn:53 - Line number 30788: maximum field length exceeded

ソリューション

This issue has been resolved in FPGA Express 3.2 (Foundation 2.1i) and newer, as timing
constraints are no longer written into the XNF. They are now placed in an NCF file.
