Xilinx Map vs IOB tri-state with clock enable...

Apr 25, 2006 1 Replies

I'm using XST 8.1 SP3 with a Spartan3 design. I'm trying to use both the output and tri-state flip-flops in the IOB, but the Xilinx tools are fighting me.



If I code my logic as:



always @(posedge ifclk) amb_data_enable


Here's more info....

I re-coded to get rid of the clock enable thinking that would trivially fix my problem:

reg data_on; wire data_enable; always @(posedge ifclk) if (dclkp) data_on
