What is the correct polarity of the accum_sload and sload_accum ports of the Arria10 Altera_Mult_Add IP Core? - What is the correct polarity of the accum_sload and sload_accum ports of the Arria10 Altera_Mult_Add IP Core? Description The sload_accum port of the Arria® 10 Altera_Mult_Add IP is active high. The accum_sload port of the Arria 10 Altera_Mult_Add IP port is active low. This is incorrectly stated in the 2016.06.10 version of the Integer Arithmetic IP Cores User Guide: https://www.intel.com/content/dam/altera-www/global/en_US/pdfs/literature/ug/ug_lpm_alt_mfug.pdf Resolution A future version of the Integer Arithmetic IP Cores User Guide will be updated to reflect the correct polarity as stated below: sload_accum: Dynamically specifies whether the accumulator value is constant. If the sload_accum port is high, then the multiplier output is loaded into the accumulator. Do not use accum_ sload and sload_accum simultaneously. accum_sload: Dynamically specifies whether the accumulator value is constant. If the accum_sload port is low, then the multiplier output is loaded into the accumulator. Do not use accum_ sload and sload_accum simultaneously.
