Critical Issue
Description
FIR Compiler II intermittently inserts unnecessary delay registers
between a coefficient storage register and the multiplier that uses
that coefficient.
This issue may cause the first FIR iteration after a coefficient
update or reset to be calculated using the wrong values. Once the
correct coefficient value propagates through the delay registers,
subsequent FIR iterations will be calculated correctly.
This issue affects FIRs that use reloadable coefficients. FIRs that
use constant coefficients are not affected.
This issue is fixed in version 12.0 of the FIR Compiler II MegaCore function.
