10.1 NGDBuild - "ERROR:TSDatabase:36 - Specification "tsa" is defined in terms of a specification with TSid "TSclk", which does not exist"

Description

I have the following constraint in my UCF file:

TIMESPEC tsa = PERIOD "CLK2" TSclk*2;

When running Translate, the following error occurs:

"ERROR:TSDatabase:36 - Specification "tsa" is defined in terms of a specification with TSid "TSclk", which does not exist."

Solution

TSclk must be defined in the UCF file when it is referred to in the constraint line. This TS identifier must have a unique name.
