Hi Ian,
The parameters that are being set in the mask script are not for the
delay_bram per se, but for the counter blocks underneath the delay_bram.
The delay_bram's parameters would be set by a mask above it, or by hand.
Could you attach the error message you're getting so we can have a crack at
it?
Thanks,
Mark
