  • Monte carlo analysis

    sir i am ,, using IC 5.10.40 in cadence , ,, I want to make monte carlo analysis for my circuit , but my seniors here are telling that monte carlo is not working here in the version ,, how can i check that ?.. i am just beginer , please reply ,,

  • Fully differential opamp caluculations

    I made this schematic and I simulated this I am getting gain ~40dB and UGB 20Mhz, I want to do stability analysis for this fully differential ckt , And I want to find out --- CMRR --- PSRR ---Loop gain (from stability analysis ) How I should use cmdprobe to do stb analysis , please help me

  • PSS Analysis's reliability-Difference between time domain response in PSS and Tran analysis

    I'm designing a wide band matching network to drive an antenna.The output pulse at the output of pulse generator is delivered to one N1PORT as the antenna model thet refered to a S1P file with value from 1GHz to 8GHz. I want to use this interface between antenna(S1P port with n1port component) and...

  • MMSIM10.1 -- a release for PA/Transmitter Designers

    Fast Envelope Analysis for APSRF and EVM calculation (+ constellation display) feature in ADE/Ocean was instroduced in MMSIM10.1. Comparing to regular Envelope analysis, fast envelope analysis could reduces simulation time from days to few hours without accuracy lose. That features are loved by PA designers...

  • Initial DC analysis extremely slow

    I designed a serializer with a PLL. I can do post layout simulation with serializer or PLL separately. When I simulate the whole system, the spectre got stuck at the initial DC analysis. After print out "Trying 'homotopy = gmin' for nodesets.", there is nothing more to output after...

  • Re: Warnings during the use of Spectre

    Hi, Lawrence Thanks for your kind help! That was useful! I solved my first and third problems, by modifying my .cshrc file. It turns out that I didn't set the right path for MMSIM and Calibre. As for problem 2, I am still bugging the person who is responsible for the licenses. Thank you again! Regards...

  • Blog post on simulator analysis & when to use what

    This free article isn't all that relevant for experienced designers, but for the novice, it is helpful: http://www.circuitdesign.info/blog/2008/11/circuit-simulator-analyses/ (Full disclosure: I wrote it.)
