    [SOLVED] TCL testbench in Modelsim

    Thank you guys for your help. Compiling the .vho and then simulating it with TCL was good idea but for just small piece of code. I took the advice from trickydicky and followed it. After lots of errors i have converted my code in .vhd code and now i am going to write the testbench for the same...

    [SOLVED] TCL testbench in Modelsim

    Writing a testbench is not a problem. The problem is instantiating the top level in my testbench and then compile it. It can be easily done when i have source code but i don't know how to include my top_level_design which is already been compiled separately and i am left with VHDL Output File (.vho)

    [SOLVED] TCL testbench in Modelsim

    Thanks Tricky (.do) file is easy to handle. I am using the same for my TCL for now.:thumbsup: Hello Kevin i am getting your point but i dont have orignal source code. That's the reason i am using TCL to varify the design, so i am trying to dump data bus output in a text file then observe the...

    [SOLVED] TCL testbench in Modelsim

    The correct way is to write an HDL twstbench, but i am bound to use the same my project where i have VHDL Output File (.vho) available with me. Extension vho is a output of Quartus(Altera) simulator tool for FPGA. And only tcl is the way i find to test the design. Now i am in some progress with...

    [SOLVED] TCL testbench in Modelsim

    I have seen some threads about people seeking help in TCL scripts when you simulate a design on ModelSim without a testbench and i am one of them. I tried to write testbench but the design i am testing is very big and not fully known to me. So i was told to test few new functionality. :bang...

    FIFO depth required for async FIFO

    This discussion helped me. Few months back i was asked question in interview "What will be minimum and maximum FIFO depth if write cycle is 80 words per 100 clock (80w/100clk) and read cycle is 8 words per 10 clock (8w/10clk) ?" And i was like not getting the question. can u help me guys. What...

    How to calculate the depth of FIFO and what are the designs contraints for it?

    what will be fifo depth both minimum and maximum if write cycle is around 80words/100seconds, and read cycle of 8 words/10 second??

    BT.656 video protocol

    ur effort is appreciable. i have this document, i read many document for this BT 656 n SMPTE 292. An this basic info is already extracted. i m receiving SMPTE 292 signal and after receiving this i have to decode to BT 656. so i want to get knowledge of SMPTE 292 decoder and then convert this...

    FPGA/ CPLD as a substitute for Microcontroller?

    i have used these fpga with my senior's and we blow up that fpga, so be careful with the use the same. - - - Updated - - - i think it looks good for u rollingEEE it got FPGA, an on-board FLASH module to store your configuration and a operation on 5-volt tolerant I/O.

    verilog - VHDL variables

    can't we use a std_logic_vector(value downto 0), were value is greater then we need and we take values as x ((value-3) downto 0) <= y ( value downto 0); -- rest of bit's will go to overflow like :- a <= d(msb downto X); b <= d(X-1 downto Y); c <= d(Y-1 downto 0);
