LogiCORE Multiplier v8.0 - The SCLR does not reset the upper bits of a DSP48-based 35 x 18 multiplier. Why?

Description

The SCLR does not reset the upper bits of a DSP48-based 35 x 18 multiplier. Why?

Solution

This is a known bug in the reset of the Multiplier v8.0, and is fixed in Multiplier v9.0. 

 

The way to work around this issue is to infer registers with a reset at the output of the multiplier, using HDL.
