Critical Issue
Description
Signed multipliers are interpreted as unsigned multipliers, resulting in unexpected output data from the following cores:
2D finite impulse response (FIR) filter
Color space converter (CSC)
This issue is not observable in simulation, but is visible at the hardware or gate-level simulations in version 12.0 release for the Stratix V, Arria V, and Cylone V devices.
Resolution
None.
This issue is fixed in 12.0sp1.
