  • Bringing MEMS Design To The Mainstream

    Micro-electrical mechanical systems ( MEMS ) have been around for years, and have found their way into high-volume applications such as automobile air bag controllers, GPS systems, and inkjet print heads. But MEMS devices such as accelerometers, gyroscopes, RF switches and pressure sensors are not as...

  • Things You Didn't Know About Virtuoso: IC 6.1.4 ADE Enhancements

    I'm not going to beat around the bush here. I could tell you about all the things that are new in ADE (Analog Design Environment) in IC 6.1.4. I could tell you about the fact that the individual subwindows are now resizeable, rearrangeable (is that a word?), undockable and tabbable (I know that's...

  • Disappearing geometry

    I have a pCell where contacts are repeated as the width increases - pitch = 12 .0 repeats = (wu + 4.0)/12.0 This works as expected for all widths EXCEPT the default, minimum, width in the CDF which is 8.0. When "wu" is 8.0, the contact disappears. If I make the CDF default 7.0 then the contact...

    Hello I try importing the final verilog (.v) file generated by SoC encounter so I can do LVS for a mixed signal design, but ihdl.exe doesn't generate schematics. The beginning of the log file says (scgp is the digital library name in icfb): @(#)$CDS: ihdl.exe version 5.1.0 12/16/2007 23:32 (cicln04...
