Connecting Symbols in a .bdf file in Quartus II

[GeekWizard]

Hello everyone,

I have designed two separate .bdf files and then made their corresponding symbols.

I have then created a new .bdf file and then trying to put all these symbols and connect them together.

However, it seems to not generate anything on the output waveforms. All the blocks work fine independently but do not if connected together. I do not get any error message.

Can anyone point out what I am missing? Are there any extra measures to be taken when connecting symbols in a .bdf file ??

Thanks

two ways

1. put all the designs in the same directory and same project, then to compile and test.

2. instead of .bdf output, take .vqm file of the two design and put it in the design
this will always work.

regards,

baba

1. I tried the first option but it does not work. I had put all the .bdf and .bsf files in the same directory copied from their previous directories and then compiled but no still results.

2. I am not entirely clear how to use the .vqm files. How do you insert or combine them in a .bdf file ? Or do I have to write a top level vhdl code file to combine them ?


Thanks for your help.
