How can I direct run nios programmer on epcs?

thank you.

can I use the serial RAM for example 23k256,because the FPGA pins is used full,do not use the parallel RAM.

`timescale 1ns/10ps

module M23K256 (SI, SO, SCK, CS_N, HOLD_N, RESET);

input SI; // serial data input

input SCK; // serial data clock

input CS_N; // chip select - active low

input HOLD_N; // interface suspend - active low

input RESET; // model reset/power-on reset

output SO; // serial data output
