error: No .vcd file found

[Sanjana Bobde]

Hi,

I am trying to implement the VHDL code to read images using FPGA. I am facing an error.

Can someone help me out to solve this error.

Finding VCD file...
No *.vcd file found. EPWave will not open. Did you use '$dumpfile("dump.vcd"); $dumpvars;'?  

Thankyou,

Hi,

I think this line points out the error:  # RUNTIME: Fatal Error: RUNTIME_0048 design.vhd (36): Cannot open file "IMAGE_FILE.MIF"; no such file or directory.  Did you copy and paste the example data into a file and name it IMAGE_FILE.MIF and then add it to the design files?

HTH,

Lee.

[Sanjana Bobde]

yes, I have copy pasted this program. What should I do to remove that error.

[EDA Playground]

It's trying to load a file called IMAGE_FILE.MIF. EDA Playground tabs are files, so you need to find this file and upload it as a new tab. (Click on the plus sign to create a new tab.)
