Dears I am trying to do calibre extraction for inverter but i am facing this problem ERROR: Could not find cell mapping for device nch. Ignoring instance M0. ERROR: Could not find cell mapping for device pch. Ignoring instance M1. However the LVS passed successfully, could you please help me in that. I am using TSMC65n
Hello, I am facing a problem while doing a post layout simulation of a simple inverter chain.I ran a transient analysis on current through voltage supply node(minus terminal) with an intention to know the current flowing through the circuit at different instant of time. Below is my Test Bench circuit. 110156 Unf
I have the skill file for the layout of a simple inverter chain. Do anybody have any idea how to do the DRC, LVS checks for the layout and thereby do the extraction followed by post layout simulation to get the AC response through a script?? There are ways to get the ac responses for schematics from OCEAN scripts. So is it possible to write scripts
dear all, i have implemented an inverter in synopsys custom designer. and now i am trying to do DRC, LVS and Parasitic extraction. Problem is when i do the DRC check then i could pass it. but when i try to go for LVS, i get errors. can any body tell me whats wrong with my procedure. i am attaching the relevant files. I using synopsys f
I did a simple inverter layout & run Calibre LVS here is the LVS extraction report ############################################################# ## ## ## C A L I B R E S Y S T E M ## ##
Hi I ma trying to re simulate an extracted design and getting strange results. It is acting as if all the inputs and outputs of sub blocks are floating and their is no interconnection between sub blocks. Background: I have tried extract and simulate one level say an inverter and it works fine but when I try a higher level design say two inver
Hello I am using the 45nm IBM-SOI toolkit provided by MOSIS for my custom design with Cadence Virtuoso. Right now i am working on the layouts of my design. I am using the Calibre tool-suite for DRC/LVS/extraction. For a simple inverter although my design is DRC clean when i try to run an LVS i find that the tool is not picking up the ports in
I'm using AMS hit kit. Technology is c35b4. I draw a simple inverter. And try to do drc. And there are errors in divaDRC.rul "Error=Duolicate layer net allowed. The results will not be as expected. 264: net_poly1=geo0r(poly1_cut poly1_cut) What does this mean and I correct it..
I want to extract R, L and C values after layout in cadence from a inverter circuit(operating freq is in GHz). In RCX extractor, if i choose RLC extraction, it is gong to ask "enter inductance net". I want to know what to include if i have a inverter circuit with C as the laod capacitor. Also i want to know how to have the inductance in (...)
Before simulation of Ur RO try to take a inverter as a simple testcase and try ti run pre/post simulation. Beginning from 90 nm technology process and deeper (65nm and 45nm), well proximity effect becomes more significant in alteration of MOS device characteristics ?Pre-layout simulation (schematic + NoRC mode) ?Post-layout simulation ?Po
