My signals are on the scale of microvolts, and in the open loop configuration I have a voltage gain of ~40 db to my bandwidth (~10KHz). I know it is weird using open loop, but the absolute gain can vary a decent amount before I would saturate my output. I have a lot of constraints for this...
Hello,
I am designing a diff amp in cadence virtuoso with the following architecture:
I am new to designing these amplifiers, so I started with noise/power constraints and worked my way from there. At the end of the day, I have the perfect AC response, gain is great, noise specs and power...
I'm designing an Analog MUX in IC in cadence virtuoso that will be addressed using a 4 bit decoder (so a 16:1 analog MUX). My first idea was to use a transmission gate (nmos + pmos with inverter). However, my adviser thought this was overkill and that just an nmos would work. Here is some info...
Re: "calibre view generation encountered a fatal error" but spectre PEX extraction wo
Just checked and I do have read and write permission.
Okay so here is one lead I had. I talked with mentor people and they said add this to your source file "export CALIBRE_ENABLE_SKILL_PEXBA_MODE=1" This...
Re: "calibre view generation encountered a fatal error" but spectre PEX extraction wo
No, there are no other errors in the CIW besides the one I reported in the original post. I am sure that my ground node name I entered is correct and present on my layout (it would fail LVS if this were not...
Re: "calibre view generation encountered a fatal error" but spectre PEX extraction wo
My pins are on MET1 - pin layer, my label is on MET1 pin layer (there was no label layer, and I got LVS to work by putting it on this layer), I am not using any illegal names.
Yes, I included the PEX rule...
Re: "calibre view generation encountered a fatal error" but spectre PEX extraction wo
I see a file created called "calview.log" in the folder I run it from (the name assigned in the calibreview pop up menu) and in the file this is all that is there:
//
// CalibreView Settings:
// Netlist...
Re: "calibre view generation encountered a fatal error" but spectre PEX extraction wo
Sure, thank you! I am following a tutorial like this
1. In calibre PEX window in rules tab select the PEX rules file from my foundry (I've looked at it and it seems to look like a pex rules file)
2. In...
Re: "calibre view generation encountered a fatal error" but spectre PEX extraction wo
Thank you for the reply! I have tried running it dozens of times, changing things to try to get it to work...no luck. Do you use calibre view as the export format? I'm still trying to figure out what is the...
"calibre view generation encountered a fatal error" but spectre PEX extraction works
Hello,
I am using cadence (version 16) and calibre.
I have a DRC and LVS clean layout and was able to extract a spectre PEX netlist and simulate it from the command line. However, it seems much easier to use...
