Using (TI) Pspice model in Virtuoso

B Josime
 Hi all,

 I'm doing some simulations of a filter cicuit that uses comercial AI (ina326 from TI). I've downloaded the Pspice model available at TI and i've copied the INA326.lib content between ".SUBCKT" and ".END" to the Hspice.hsp file of the cell_view that i've created. Untill here everything's normal.

 But when i do the simulation, it doesn't work due to

"Missing or corrupt .oa file in cellview 'xxx/ina326/spectre cmos_sch schematic Hspice'. The OSS netlister can only

process cellviews that have a valid .oa file. "

Does anyone know how o help me fix this??

  • Well, Pspice models do work in "Cadence" ;-) (Pspice is a Cadence product). However, they don't work in Spectre (another Cadence product). Whilst we get requests now and again, using models intended for Pspice is not that common an occurrence because the focus of the simulators is somewhat different; Pspice is mostly used for board-level design, and spectre for IC design. Getting full language coverage of the Pspice language for the odd use here and there is a lot of work for not that much (overall) benefit, as you can imagine. So it's not beaten other things in the prioritization battle.

    Of course, if you're the one who happens to want to do it, it's clearly a shame!
