Symbol
Combinatorial delay is less and pipelined performance is higher when multiplying input data with less than 18 bits.
The PREG register is typically used in both single-stage and two-stage pipelined multiplier implementations.
Input registers AREG or BREG are typically used when inferring a two-stage multiplier.
R
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 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
