I am working of quartus tool. should anybody tell me how to read and write on memory of stratix v fpga? how to make test bench for it? i just want to read and write on chip memory (ram) in mlab of stratix v.
Hi I have created a controller for DDR3 with the MIG. MIG output folders are example_design and user_design. according to MIG report : - example_design: This folder includes the design with synthesizable test bench. - user_design: This folder includes the design without test (...)
hi, i am trying to use the MegaWizard tool for floating point division from Quartus, but when i run the test bench for the design i keep getting this error message Fatal error in Process memory at C:/altera/12.0/modelsim_ase/win32aloem/../altera/vhdl/src/altera_mf/altera_mf.vhd line 39809 # HDL call (...)
Hi Dave, Wont it be better to use this for-loop in test-bench and load the calculated values into RTL during reset? AM nt sure. Pl guide.
Hey, just tried it: Before begin of architecture: signal write_data_buffer:= ReadText("GPUdata.txt"); And then RAM <= write_data_buffer; or RAM(to_integer(unsigned(Write_addr))) <= write_data_buffer(to_integer(unsigned(Write_addr))); In the testbench my output is completely undefined When I try: RAM(to_integer(unsigned(Write_addr))) <= (...)
To read array from test bench use: initial $readmemh("data.txt",mem); In above case you read hex data from data.txt file to read memory data. You can use for loop to traverse through all the location. To write data to text file use: $dumpfile("data.txt"); Hope this helps
Large Look Up Tables are really ROM memories. You can instantiate a memory in verilog and then give each memory location an initial condition in the test bench. I have also loaded these testbench memories from an external file in the test bench. In real (...)
