Cadence Virtuoso:: CMOS Inverter || Part-1.

This video demonstrates the design of CMOS inverter using Cadence Virtuoso Tool. Here, transient and dc analysis of performed along with the simulation results.

[@rinakundu5841]

Very clear explanation, Thank you so much Sir

[@dr.hariprasadnaikbhattu]

You are welcome

[@Duyneee1103]

Thank you sir for helping me, thanks to this video I can submit my homework

[@dr.hariprasadnaikbhattu]

You are welcome

[@YixuanZhang-c7g]

Hi sir, it's a practical explanation but can you pleased explain why connecting wires and pins like this allows us to create an inverter?

[@dr.hariprasadnaikbhattu]

Hi, They are used for creating large designs in the hierarchy. Simple schematic also works at Transistor level.

[@nagesherugu6899]

Excellent explanation..

[@dr.hariprasadnaikbhattu]

Thanks You

good explaination sir

[@dr.hariprasadnaikbhattu]

Thanks and Welcome

[@Goutham-qd6ly]

Nice and smooth explanation sir. Thank you :) for your efforts

[@dr.hariprasadnaikbhattu]

Thanks you. Appreciate for the response.

[@alex_semin]

Hello, thank you for your videos! I installed Virtuoso but i dont have gpdk, how to install this?

[@dr.hariprasadnaikbhattu]

If you have gpdk library then there are method to do. Search on KZbin to add gpdk

[@JoySutradhar]

Sir, I am getting the same error while simulation. Could you kindly elaborate the error or the vpulse object property that you have modified?

[@dr.hariprasadnaikbhattu]

Hi provide the pulse input (voltage1=0, voltage2=1, risetime=50p, falltime=50p, pulsewidth=10n, period=20n)

how to fix ERROR (SFE-1997): "input.scs" 27: V1: parameter `fall': The parameter `_gpar0' is used but not set. i think you drop howto fix, pls fix it thanks

[@dr.hariprasadnaikbhattu]

Hi, I don't know about that error. It may be related to model file missing

[@nhellyx]

hi sir! which button you press on keyboard to show values: 24:53

[@dr.hariprasadnaikbhattu]

Hi I think it is shift key to select multiple signals

[@ismailmchichou626]

Hello sir thank you very much for this excellent explanation, please I have the same version of Cadence that you have, is there a method to add the library gpdk 180 nm

[@dr.hariprasadnaikbhattu]

Yes, use library path manager from CIW window

[@vajramanasapalgunahv6019]

hello sir, i did as you have shown in the video. But, before the launch step we have to save and continue right, there it is showing 2 error in the Vout and the output pin of the NAND gate, how to solve this?

Hi, I could not get your question

[@kaverihatti7472]

Sir, how to input vector data to the city in cadence Is it possible to to give the inputs from the matlab to cadsnce

[@dr.hariprasadnaikbhattu]

No it is not possible to give input from matlab to cadence

[@nikithaAthinamoni]

sir can you explain finfet technology

[@dr.hariprasadnaikbhattu]

Hi, I think I have answered your question.

[@ashishmaram1049]

Hi sir . Im unable to select the wires and nodes as you did sir at 20:51

[@dr.hariprasadnaikbhattu]

Hi, just enable the default selection filter in main window of Cadence Symbol looks :pointer and tick symbol left of transistor with tick.

[@riyazuddinmohammed3508]

sir, you design pmos and nmos with same W/L ratio in Actual w/l ratio of pmos should be 2.5 times greater than pmos i think but you got DC waveform Correct How is it possible?

[@dr.hariprasadnaikbhattu]

Appreciate for the review. I got the DC characteristics OK. But important is has it crossed at midpoint (half the value of input). If it is not crossing then use pmos width Wp=2.5 that of Wn of nmos.

YOU DONT NEED TO CREATE A SYMBOL TO SIMULATE. SYMBOL CREATION IS TIME CONSUMING. ALSO YOU MISSED IMPORTANT COMMANDS LIKE PRESS ESCAPE KEY ETC.

[@dr.hariprasadnaikbhattu]

Hi, symbol creation is optional. If you want to simulate circuit directly you can simulate it without symbol. Generally symbol is used for hierarchical design.
