Plz ! help me ....
I got a problem that makes me confusing . I must write a program that can read and write data from a physical disk by VHDL and simulate by Max+Plus II . But I can't write by Max+Plus II . It 's error ..... So , How can I write ..................
Can you show me more e_books write about that .....
 

Check out the textio library.

Oh thank for all ur help .....
but a new problem occurs that MaxPlus doesn't support for access type that the most important tool for access line string so.........
 

Are you trying to get the FPGA to interface to the disk or just with the simulator?

You cannot synthesize any textio functions.

Cheers,

Oh.....
I do this job just to simulate for acknowledge >..... but with altera I can't do any simulation because they don't support acess type so we can't use the pointers.....
.....
 

Hi kangta

Check the MaxPlusII help :
File I/O cannot be synthesized; therefore, calls to TEXTIO functions are ignored.
