    LVS error: schematic and layout mismatch. Port undetected.

    Re: LVS error: schematic and layout mismatch. Port undetecte Maybe. I'm not familiar with FreePDK. I used the information from NCSU EDA Wiki.

    LVS error: schematic and layout mismatch. Port undetected.

    Re: LVS error: schematic and layout mismatch. Port undetecte Of course. green-colored dot-filled layer - means ACTIVE (hole in mask oxide), seems like light blue-colored triangle-filled layer - means NIMPLANT layer (to form N+ areas). This last layer missed for NMOS. In result no N+ drain and...

    How to simulate SPI interface in ADE?

    spi profile clock If you use MMSIM 6.0 or higher version it is possible to set digital signals by means of digital vector file otherwise better to use ULTRASIM.

    Calibre LVS error different number of ports

    calibre exit code 4 The label "out" crosses M1 on source and drain NMOS. Therefore "out" and "gnd!" shorted. Why the "gnd!" and "vdd!" shorted to tell on image it is difficult. It is better to reduce font height in labels so that they were completely inside corresponding metal. For marks it...
