    Which companies fabricate ASIC based on your design files?

    Re: fabrication of ASIC No company will facbricate your design based on your design file... You'lll need to confirm to their design file and other design constrainsts to get it fabricated. and comments above regarding single chip are true.... You should try using FPGA in case its possible...

    How to fix LVS error warning!

    I've not used Assura, but in Hercules and Calibre , such warnings are controllable using certain options. May be you can look for some similar option to modify your runset and give it a try.

    How do I add Physical text to a GDS ?

    I am afraid that you've got the question wrong....more appropiately I did not provide proper explaination. I don't want to use any layout editor ....that is quite simple. I just want ... GDS1------> DO SOMETHING -------> GDS2 (with added texts) DO SOMETHING : can be a script. If i;ve a...

    What is the standard RFID chip size (gate count)?

    Re: RFID I guess that widely depends on your design and application. I've once used an active RFID chip with over 500 gates with a mix of analog and digital. But if the design and applications are basic and simple you may come up with a design that used in all less than 100 gates.

    How do I add Physical text to a GDS ?

    lesearchhierarchy Hi friends, I've a GDS and i have the coordinates and the layer number where I'd like to put text. The original GDS has no text, How can i write another GDS (or modify the same one) so that it contains the text along with original goemetries. ?? Thanks,

    Does GDS supports text ?

    Hi friends, While making layouts we usuallt text various nets and ports, and devices. Is this info contained in GDS too, if I write a a GDS out of my layout ? or this is only for user's reference at Layout and verification tool stage ???/ If no, Is there any way to put text in GDS ...

    What can we do with junction temperature of a transisto?

    Re: Junction temperature What do you mean ? Do you want its effects on the device performance ? or the applications of junction temperature ? Junction temperature is becoming more crucial now a days and can impact the device performance sometimes. A high junction temperature will contribute...

    What do you mean by 2.5D extraction-based RC?

    Re: RC Extraction 3D for sure is most accurate as rightly pointed by urslen, However we do not always go for 3D , it varies from design to design. 3D takes lot of time and produces lot of data for analysis and simulation.
