Implementation of Digital PID controller in FPGA

I'm trying to implement a PI controller in FPGA using schematic entry method in altera quartus II . I'm using the following equivalent PI controller equation, c(n) = c(n-1)+kp*(e(n)-e(n-1))+Ki...

How about the Max7000 ,I got one free . is it plenty of logic for a PID controller?

Not at all. MAX7000 is a CPLD, a reasonable solution for pure digital logic designs. Even the largest MAX7000 with 512 macro cells won't allow more than a rudimentary (e.g. 8 bit data width) controller. A recent development kit like DE-0 Nano would make much more sense.
