<@U01819B63HP> how to do a simple calculation in the parameter list for lvs
The following code does not work
`lvs_format="@spiceprefix@name @pinlist @model le=@El*1e-6 we=70.0n m=@Nx"`

<@U069XNVQM4H>:
`lvs_format="tcleval(@spiceprefix@name @pinlist @model le=[expr @El * 1e-6] we=70.0n m=@Nx)"`

bracing the `expr` expression will make it faster:
`lvs_format="tcleval(@spiceprefix@name @pinlist @model le=[expr {@El * 1e-6}] we=70.0n m=@Nx)"`
put a space at the end of a @xx parameter in the `expr` to avoid having to escape the following non space character.

<@U01819B63HP> this solution worked perfectly but I would like to know if it is possible (I think it is ) to calculate this expression `lvs_format="tcleval(@spiceprefix@name @pinlist @model le=[expr {A * B}] we=70.0n m=@Nx)"`   where `A` and `B`  are evaluated separately using `tcleval` . I have some calculations and just for making it clean it would be nice to do it in a few steps.

The `minimal`  DRC is the minimal set of DRC rules which ensure no errors.  The `maximal` extends the minimal DRC ruleset by reliability rules.
