描述

Why is the fractional width on the "reload_tdata_data" port no longer dynamic in the FIR Compiler?

Previously this could be configured as Fix_X_Y in the GUI.

解决方案

Previously, the fractional width of the "reload_tdata_data" port of FIR Compiler IP was dynamic and it depended on the user configuration (GUI settings) which created some inconsistency. 

Therefore, to make it more consistent and general, the fractional bit is always maintained as '0' starting from the 2013.3 release.

The old designs can be used by introducing a Re-Interpret block between the source block and the "reload_tdata_data" port of the FIR Compiler.

This will not break any functionality.
