The numbers in this table are based on the operating conditions set forth in
The PREG register is typically used in both single-stage and two-stage pipelined multiplier implementations.
The PREG register is typically used when inferring a single-stage multiplier.
Input registers AREG or BREG are typically used when inferring a two-stage multiplier.
Combinational delay is less and pipelined performance is higher when multiplying input data with less than 18 bits.
Combinational 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 after the active transition at the
CLK when using only the PREG output register (AREG, BREG
registers unused)
Data hold time at the A input after the active transition at the CLK
when using the AREG input register
Data hold time at the B input after the active transition at the CLK
when using the BREG input register
Internal operating frequency for a two-stage 18x18 multiplier using
the AREG and BREG input registers and the PREG output
register
