how to specify different .dspf file for different instances of the same cell

Karev11

Hi,


I'm wondering if it's possible to specify different .dspf file for different instances of the same cell for post layout sim?  I know it's staightforward if there are extracted views, through config-tree thing, but in this case I only have extracted .dspf file.

thanks,

Kev

    Kev,

    I don't believe it's currently possible via the dspf_include mechanism (specifying the DSPF file on the Setup->Simulation Files form). Instead, you'd have to use the "old" flow which is to set up the CDF for the cell to have the termOrder in the spectre simulation information to match the order of the subckt header in the DSPF, and then pick view to use->external SPICE (or something like that) in the hierarchy editor for the instances you want to use each DSPF file. You might need to edit the DSPF files to give different .SUBCKT names though - it's not obvious to me that that would really work (I haven't tried it).

    This might become possible when DSPF view support is fully ready (it's coming soon), but the best bet for now would be to go to customer support to ensure that your requirements are fully captured.

    Regards,

    Andrew.
