**broken link removed**

Im sure there are many others.

I assme this is for a testbench only, as this cannot be synthesised onto an FPGA.

is there is any method by use of which i can read values from text file and display it on fpga??

Yes, but niot directly in vhdl. You'll need some form of comms connected to a pc and send the data from a pc (maybe a uart or something
