Does the ALTMULT_COMPLEX IP support unsigned operation in V-series and 10-series device families?

Description

No, V-series and 10-series device families only support signed input representation for the ALTMULT_COMPLEX IP. Change the ALTMULT_COMPLEX IP from unsigned to signed input representation before migration from older families to any V-series or 10-series device families.

Resolution

Before changing to V-series or 10-series, peform these steps to change the design from unsigned to signed input representation:

1. Input representation set as signed
2. Increase input data width by 1
3. Add value zero at the MSB of the input data
