Critical Issue

Description

Some multicycle variable interpolation filters with high interpolation factors may generate incorrect output.

This issue affects MCV interpolation filters with high interpolation factors and forced non-symmetric implementation where the pipelining level is set to greater than 1 for higher fMAX.

The produced output does not match the expected output.

Resolution

Change the pipelining level to 1. This change may result in lower fMAX but the filter output will match the expected output.
