Spartan 3A ICAP requirements

Description

What is the MAX Frequency that the Spartan 3A ICAP can run at?

How do I apply constraints to the ICAP?  

What constraints cover this path? 

Solution

100 MHz is Max frequency that you can run the ICAP at.

To properly cover the ICAP path you will need to use a NET MAXDELAY constraint. 

A period constraint will not work.
