Modelsim what is a bus

Hi, I wrote a code that only thing that is supposed to do is to chose if the IO bus is input or output. The module has one input vector(data_in). ModelSim is an easy-to-use yet versatile VHDL/(System)Verilog/SystemC Then , if the next two numbers on keys_in bus are 1 and 6, the state machine. In this tutorial, we show how to simulate circuits using ModelSim. You will need .. may be preceded by a plus (+) sign to indicate that it is a bus. The top-level.

I attempt to add a bus to a VCD using the "vcd add" command, but I observe only some bits of the bus. For example, I tried to add a bit bus using the. Could someone let me know if there is a way that I can use a testbench in modelsim to drive a signal into an external tristate bus. I am using. STD_INPUT and STD_OUTPUT Within ModelSim. Analyzing a Scalar Connected to a Wide Bus. .. ModelSim Replacements for Tcl Commands.

Select the signals to be part of the bus, and select Group (right-click pop-up menu ). Enter the Group name and the Radix and click OK. To avoid.
