Combinatorial multiplier propagation delay from the A and B inputs to
the P outputs, assuming 18-bit inputs and a 36-bit product (AREG,
BREG, and PREG registers unused)
Clock-to-output delay from the active transition of the CLK input to valid
data appearing on the P outputs when using the PREG register
Clock-to-output delay from the active transition of the CLK input to valid
data appearing on the P outputs when using either the AREG or BREG
register
Data setup time at the A or B input before the active transition at the
CLK when using only the PREG output register (AREG, BREG
registers unused)
Data setup time at the A input before the active transition at the CLK
when using the AREG input register
Data setup time at the B input before the active transition at the CLK
when using the BREG input register
Data hold time at the A or B input before the active transition at the CLK
when using only the PREG output register (AREG, BREG registers
unused)
Data hold time at the A input before the active transition at the CLK
when using the AREG input register
Data hold time at the B input before the active transition at the CLK
when using the BREG input register
