6.3i XST-The TIG constraint does not work in HDL code although the constraint guide specifies it

描述

Keywords: constraint, TIG, HDL, code, NGDBuild, Translate, False, path

I followed the constraint guide to put a TIG constraint, but NGDBUILD does not take it into account or generates an error.

解决方案

This is fixed in ISE 7.1i.

In 6.3, the TIG constraint is not supported in the HDL code.

To work around this issue, you can use a "*.xcf" file (synthesis constraint file).
