Pspice model of memrister running in Virtuoso

Ranjun,

You posted this originally on the end of a 9-year old thread, which the forum guidelines ask you not to do. Please read them. Also, sending me a friend request with the same question will not get it answered any more quickly, and I generally decline all friend requests on the forum because questions should be asked in the forums, not to me personally. So I split your question off from the original thread and moved it to a suitable forum.

I took the file above and created a "pspice" view of a cell in Virtuoso. The first thing is that it does is complain about the .params line. That's because the statement in PSPICE should be .param - if I remove the "s" from the end of .params and change to .param, everything appears OK. I can create a symbol from the model and then reference it in a schematic (I'm not sure what the meaning of each pin is or any of the parameters or how it's supposed to behave, but a simple simulation ran OK).

Andrew

I'm sorry Andrew for not complying with guideline before. I'll make sure ,I'll follow all guidelines from now onwards.

I am thankful to you for your time and response.

I wrote the Pspice code using pspice text editor in virtuoso and made symbol out of it and drawn the schematic out for just checking the behavior of memristor.

Schematic is shown below:

Parameter for vsource is as follows:

Made the Config file out of it,( am I taking analogLib as spectre as view, is that correct?)

But while running in ADE_XL, I'm not getting the input waveform as sine as well, could you please help me finding out the error or something which i might my skipping due to my limited knowledge.

Output:

Thanking You

Sincerely

Ranjan 

Hi Ranjan,

You don't have a ground symbol in your schematic, so the simulator ground will be assigned randomly. Please add a gnd symbol from analogLib to the wire between negative terminal of the vsource and the BE pin.

I didn't repeat your test, but that's probably what's wrong.

Andrew

Andrew, I added the ground first, I didn't work out so I removed the gnd still, Vsin voltage as input sine waveform didn't come. As you said to add gnd, I again added and ran the ADE_XL in config mode, still output remain same at 0 V as input, which inturn not causing any change in threshold based memristor.

What shall I do now?

Any suggestions would be highly appreciated.

Thanking You

I just noticed that your config has a very strange set of views used, and also has no stopping views. Not sure that this is the reason, but it's not good. When you create the config view, click on the "Use Template" at the bottom and pick "spectre". Set the top-level design appropriately, but your view list should be:

spectre cmos_sch cmos.sch schematic veriloga ahdl pspice dspf

and stop list:

spectre

If this doesn't work, please go over the output point in ADE XL and use Right Mouse->View Netlist (or something like that) and share the contents of the netlist that is shown.

Andrew

Yes Andrew, It worked. Thank you so much. 

I'm really grateful to you for helping me.

Warm Regards

Ranjan
