Question

2. Within Altera Quartus FPGA development software, once you created either RTI or Schematic design, ) how can you create Symbol file and how can you place it onto design window ?

Answer 1

ANSWER:

How to create a symbol file:

File---> create/update----->create symbol files for current file----> save it with an appropriate name

-------------------

How to place it onto design window:

Select another file on design window-----> click on symbol image from the above bar-----> click on project-------->

select the appropriate symbol file.

and the symbol will appear on the design window

EXPLANATION:

After creating the Schematic design , choose the File and then choose the Create or Update option then select Symbol files .The symbol file should be named same as the current active circuit diagram with the extension .bsf .

After creating symbol file to view/ edit any symbol open the file with extension .bsf , for example : mul.bsf , the logic symbol present in the file will be open for example a logic symbol of Multiplexer.
The output and input signals of a multiplexer can be placed by dragging their lines connected to symbol box.
The symbol file created can be placed in design window, click on .bdf extension tab and then on edit and insert symbol options, and select mul.bdf, by using the mouse place the image in block editor grid . The files .bsf and .bdf can be used by any other project by just copying the files into required project directory.
