Spectre/APS: how to save only subckt and some level below it

enzhu

I think this might be an old topic, but I just could not locate some of them. 

My question

1> How to save all voltage signals from a certain block and its sub levels? For example, we have a fullchip and subblock called buck_core. I would like to save all the voltage signals on buck_core level and its 3 level down. 
2> How to save port current signals from a certain block and its sub levels?  Device current is optional to save. 

Thank you.

  • I'm having to make some assumptions here, because you didn't give any indication of the tool versions you're using, or whether you want to do this from ADE or from a spectre netlist. That's even assuming that it's spectre you're using here, since you didn't say.

    Anyway, in current versions, in ADE, you can use Outputs->Save All and then on the form there's a "Save by Subckt" tab:

    You can then choose to save the voltages within that instance, the currents too - and next to the checkmark you can also set the hierarchy depth to save to.

    I think it was during IC617 that this changed to be on the Save Options form; prior to that it was under the Outputs->To be saved->Select by subckt inst menu (or something like that; I didn't check back since I wasn't going to spend too much time on a guess that this was the info you needed).

    If you're using a really, really old version, then this would need to be done by including a spectre include file, with a save statement, but let's cross that bridge if this turns out not to help if you're using ancient versions.

    Regards,

    Andrew.
