IP Soft Error Mitigation Controller - Is BUFG necessary for driving icap_clk ?

Description

Is it necessary to use BUFG for driving icap_clk ?

Is it possible to substitute BUFR (or other buffers) for BUFG to reduce BUFG used numbers.

Solution

As long as there are no device limitations that restrict you from clocking the ICAP from a BUFR, then it is OK to replace the BUFG with a BUFR as long as timing is met.


Xilinx does not test the core in this configuration.

 

It is the customers responsibility to ensure that the ICAP can be clocked via a BUFR and ensure all other restrictions are met.
