Combinatorial Delay
TMULT
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)
–4.36
–4.88
ns
Clock-to-Output Times
TMSCKP_P
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(2,3)
–0.84
–1.30
ns
TMSCKP_A
TMSCKP_B
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(2,4)
–4.44
–4.97
ns
Setup Times
TMSDCK_P

CLK when using only the PREG output register (AREG, BREG
registers unused)(3)

Clock Frequency
FMULT
Internal operating frequency for a two-stage 18x18 multiplier using
the AREG and BREG input registers and the PREG output
0
280
0
250
MHz
Notes:
1.
The numbers in this table are based on the operating conditions set forth in Table 10.
2.
The PREG register is typically used in both single-stage and two-stage pipelined multiplier implementations.
3.
The PREG register is typically used when inferring a single-stage multiplier.
4.
Input registers AREG or BREG are typically used when inferring a two-stage multiplier.
5.
Combinational delay is less and pipelined performance is higher when multiplying input data with less than 18 bits.
