    HSPICE license server at each simulation?

    -- It depends on how many license tokens you have (on that license server). Normally, each running process will take one token. If you have only one license, it will have to wait for one simulation to finish. I am not sure how you run your simulation. mm

    testbench problems - outputs cannot obtained

    >>> when you run ModelSim and simulate the testbench, make sure you select the right module (testbench module) not the UUT (entity). So, you can see the waveforms. mm

    Problem in Displaying ADC Result into 7 Segment

    you need to read the datasheet first what is the output format. Basically, it is in binary, either in serial or parallel form. To display on seven segment display, you need to convert the format from binary to decimal form, use the circuit such as binary to decimal (BCD) conversion circuit. You...

    can cadence ic5141 utilize the stand cell library to layout?

    basically you can instantiate the layout cell into your layout. However, your layout library should provide a full layout view (all GDS layers) in order to get all extracted devices. If the library only provide the blackbox view, you again extract the spice from the layout, but you can get the...

    Porting FPGA IP Core to ASIC

    ASIC IP Core That's true.. if the number of unit less than 100k, the cost per unit will be very very high when using such advanced process due to a huge mask cost. For prototyping, of course, the cost of prototypes will be extremely high. But when it is in production, for example, 1 million...

    Can we use IC 5.141 to design a digital system ?

    You can use it to design digital system, but not as you want (HDL --> Syntesis -> Place and Route which require other set of tools). Nornally for IC5141, you have to draw the schematic (using the digital cell library), then create the layout using standard cells. mm,

    What is the difference between Assura and Virtouso Layout?

    Re: What is the difference between Assura and Virtouso Layou Right, there are so many tools for doing a complete IC design work. For basic IC design tools, you need schematic design entry + circuit (Spice) simulation; physical layout design, physical verification (DRC, LVS, RCX). Virtuoso...
