LogiCORE FIR Compiler v5.0 - Why do I see a glitch on the output after a coefficient reload, when using the DA FIR implementation?

Why do I see a glitch on the output after a coefficient reload, when using the DA FIR implementation?

This is a known issue that can happen under particular timing scenarios.

The following options are available to work around this issue:

Tolerate the glitch as the core will recover.
Ensure that the FILTER_SEL value is different to the COEF_FILTER_SEL value during and immediately following a reload.
Do not select ND
If ND is used, ensure that the core is run at its maximum input rate during reload or de-assert ND during reload.
