I designed a NIOS Microprocessor using the SOPC builder; added it to the .bdf file and tested it. It works fine. Now I want to add a .vhdl file to this existing project which will use some of the signals from
Refer to below: library IEEE; use IEEE.std_logic_1164.all; Entity LED_light is port ( LED_out : out std_logic); end LED_light; Architechture RTL of LED_light is begin LED <= '1'; end RTL; --- Quote End --- Hi, Do u kn...
Write the system variable to the FPGA To use the new system variable inside the VHDL code Open the changed *.vhd file with an editor like Notepad++ or Emacs. Now you can write your own VHDL code. There is an example available inside the User Manual VT System FPGA Manager.C:\Program ...
Note: There is a known issue in the tools where the Synthesis ELF will over-write the Simulation ELF. If these are the same, you will not see any problems. If you want to Simulate another ELF file, you will need to add the ELF as a simulation source: You will need to manually set...
The correct option in this case would be to open the synthesized design (loads the design from the project level) and then run write_verilog.2) In many cases, you can use the same test bench that you used for behavioral simulation to perform a more accurate simulation....
The Data Exchange Registers are used by CPU and CLA to write (but not read) to other resources within the HLC that are not directly accessible via memory-mapped reads and writes. These include HLC Instruction Memory, four HLC General Purpose Registers and three types of Counter Registers: ...

If several processes are trying to write different values to a signal, we say that it hasmultiple drivers. If astd_logicsignal has multiple drivers, it won’t be a compilation or run-time error, at least not in the simulator. That is becausestd_logicis aresolved type, meaning that its ...
As another example, were you to use a nonagentic AI code assistant for generating tests, you’d need to write a prompt like: “Create a new Java test file in a structure that aligns with the Java testing framework, preferably JUnit 5. Write unit tests that cover each function individually...
A fantastic free resource that all FPGA front end developers need to be aware of is “fizzim”. It is a tool that automatically writes VHDL/Verilog code for your state machine provided that you draw the state machine for the tool.
