      From the study undertaken in PI13 the Intel Agilex family appears to have superior performance to the Arria 10 family used by the current FDAS design and hence should improve processing times . To realise these performance gains the Floating Point Adder and RAMs used in the HSUM module have been modified and simulations will need to be performed to ensure the behaviour is correct.

    Description

      In order to create an FDAS image suitable to be loaded into an Agilex FPGA the HSUM module requires a new Agilex IP Floating Point  Adder to replace the Arria 10 IP. In addition RAMs with different clock rates on the A and B ports have to be coded differently to comply with Agilex requirements. These changes were identified and made in PI13 when the Agilex performance study was performed. However it needs to be confirmed via simulation that these changes have been performed correctly.
