[SOLVED] Any tricks to quickly create a large number of series components in HSPICE

[yklium]

HSPICE provides m=N to represent N parallel components connected.
But it seems there is no correponding HSPICE sytax to describe N series components.
Is there a simple way to quickly connect many components in HSIPE? (ex: connect 100 resistors in series)
Thanks.

PDK resistors usually has parameter s used for series connection.
However, if your element does not have such parameter, everything lies on the schematic capture program and netlister. In Cadence Virtuoso there is a trick with iterative device and net naming to achieve any wanted connections.

Thanks for your reply!
Would you mind elaborate more about how to do the trick in Cadence Virtuoso?

Example of MOSFET array with series-parallel connection - 2 branches in parallel, each with 2 MOSFETs in stack (series):

Thank you so much!
Never thought about the bus notations are able to create a matrix netlist.
This is a very informative example. I learn a lot from this.
Thanks again!
