Then you definitely need a FPGA.
Using buttons or generic I/Os was only an idea for a very simple solution.
Sure you can do it with a laptop!
For example you can send the pattern and control the generator with the RS232 serial port.
The jtag interface solution suggested by Dave is also good, but this can be used if you only need the pattern generator connected to your laptop. If you plan to deploy the design in a commercial board, you must provide a standard widely used interface:
in this case, besides RS232 you can implement virtually everything with fpga, from PCI to Ethernet, USB and so on.

Thanks, Cris!
Ok, I will switch my platform from CPLD to FPGA. And I prefer to have USB as the interface input string from laptop. Ecexpt DE0 board, what Kinds of hardware or IPs I should prepare to implement the test pattern generator?
My target: To have simple access to MCUs, in which, most of them are ARM based.
1. Enter some low power modes of MCUs
2. Access to their embflash memory, however, simple access would be enough.
