Assignment pins on FPGA

Altera_Forum · ‎08-02-2007

Hey

I want to do the assignment pin to StratixII and I want to know what is the fastest and the best way to do it?

I know that there is a way to write VHDL file with attributes, is someone know what is the format to write? and if there is format for Verilog file?

Thanks,

Shishko

You can use the altera_attribute to make these assignments in the code. Search on altera_attribute in the first book of the Quartus II handbook:

http://www.altera.com/literature/hb/qts/qts_qii5v1.pdf

(e.g. page 8-71)

I really don't recommend doing this. Pin assignments are not relevant to the HDL(what if you move to a different part, for example), and would recommend doing it in the Pin Planner(which will put the assignments in the .qsf). There is a lot more information you have available when doing it this way, rather than manually adding it to the code with no feedback process.

i don't believe altera_attribute can be used for pin assignments. You can use the chip_pin assignment as described in quartus help.
