    UMC 65nm Assura QRC problem

    Hi I am trying to do QRC with umc65nm.I am able to run QRC using Assura for the devices in library umc65ll EXCEPT FOR P_12_LLLVT.I am getting av_extracted file for all other transistors like N_12_LLLVT, N_12_LLHVT, P_12_LLHVT. Error popping up when I place P_12_LLLVT is ERROR-AVPXV-10019...

    UMC65nm Cadence QRC -Run Assura Quantus QRC

    Hi I am trying to do parasitci extraction using Assurs-QRC-> Run Assura using Quantus QRC. Technology is UMC 65nm.I am unable to figure out rule file to be laoded for it. I loaded UMC65/Rulefiles/QRC/LPE/Typ/* Can someoune help to solve the issue.

    Cadence layout view of components misaligned.

    Hi I have attached user defined library to existing technology librray- UMC.Component layouts are misaligned in my layout file...like vias are not properly aligned..contacts misaligned in layout . If i open the layout view of that device in technology library it's proper.May I know how can I...

    Simulation of active inductor linearity -total harmonic distortion vs input power

    Hi I wish to obtain plot HD3 vs Input power.I did PSS.I selected option power in mainform as shown in attachment.In the field to select harmonic I selected 3 rd harmonic and fundamental.Ploted in db Vs input power.Since Hd3=3Rd harmonic /Fundamenatl harmonic power.I subtracted fundamental...

    How to plot HD3(dB) vs Pin(dbm) in Cadence spectre RF

    I did PSS analysis and obtained power spectrum.3 RD order harmonic is obtained ,HD3=1/4(A3/A1) A3 AMPLITUDE OF 3rd order harmonic.A1,amplitude of fundamental.. How the harmonic amplitude can be plotted against input signal power,since in power spectrum its plotted against frequency.

    Simulation of active inductor linearity -total harmonic distortion vs input power

    Active inductor is a single port device.How can I connect the output port and do PSS analysis to obtain Total harmnic distortion Vs input power to characterise linearity.In the attachment I ahve shown the input port is connected and input impedance is found to be inductive.Since its a feedback...

    How to plot gm vs id in cadence

    Thanks for your reply sir.I did it.I plotted iD and gm vs vgs .Then for X AXIS, using Y vs Y option ,I chose iD. Now I can plot gm vs ID . Now I am stuck with another problem.My technology library is UMC180.When I use UMC_N_18_MM (MEDIUM MODE Transistor), I obtain all the Dc parameters like...
