They core_name_bb.v files are green checked in compilation on modelSim while the core_name_INST.v files don't go through so I just excluded these files from the project tab listing on modelSim (not sure if that's the factor).
My own code tend to have expected values but the connections to the output of these IP core modules give "z".įinal point: There are files associated with the creation of these IP core through megaWizard. Start simulating by choosing the top level module - loads and I can view the waveforms of some signals.
A broad set of intuitive capabilities for Verilog, VHDL and SystemC make it the ideal choice for ASIC and FPGA design. Compile on modelSim, all files get green checks (indicating fine) ModelSim eases the process of finding design defects with an intelligently engineered debug environment that efficiently displays design data for analysis and debug of all hardware description languages.Add existing files from my own project that is written in Verilog (a bunch of.In your case, I would suggest: Start modeling basic circuits like adder, decoders etc. In a typical IDE system such as Altera Quatus (with ModelSim) and Xilinx ISE (ISIM or ModelSim), the Verilog simulator shows the values of the variables in.
I downloaded ModelSim-Altera Software (starter edition available here) We had FPGA boards in our lab, so it was easy to actually see your model behave. The program allows you to create your own designs or choose from a vast library of simulators that you can test for various purposes. We had a hardware systems course in which some FPGA programming was done using VHDL. About A simple processor designed using Verilog and Altera DE1 development board. The starter edition has a limitation set at 10000 executable lines. This is the result of the testbench in modelsim below, the testbench verilog file has a tb to indicates that is the testbench file.
