Multiplier in Cadence Design virtuoso

[gkini19]

Hi All,

Just a basic question in Cadence Design about multipliers(m)

Say if m = 1, width= 2,4u and Length = 180n, so if I make the m = 2, only the width gets doubled and the length remains constant ( width= 4,8u and Length = 180n). Is this right ?

Yes. There may be nuances. Sometimes there are both "nf" (number of gate "fingers") and "m" (multiplier). nf is intra-device and m is number of those devices in parallel in such a case. The way you use those two params becomes instruction to the layout person, re device form although there's often sloppiness of expression early on.
