How to implement a Complex floating Point Multiplier?

Honored Contributor II



I need to implement a floating point complex multiplier for Arria 10 device, based on the Hard copy Floating point primitives. 


I found in the Arria10 handbook a drawing of the connection with one multiplier chainout connected to the 2'nd chainin, and the 2'nd multiplier works in 'Multiple-Subtract' mode. 


However I couldn't find any way how to generate thus options using the FP-IP. 


Can any one please help me?
