If the bram, adder-test HW clocked using system_clk from CLK2 it should be a snap to integrate SHA-1. Paul has written C test code that we should be able to use. <blockquote> Let's do it like this. If you don't have any objections, I'll finish my baseline project and send it to you for a review and testing next week. After we make sure that we have a stable working baseline we'll start adding cores to it. </blockquote>And just to check what we are talking about. That baseline would include: (1) novena_fpga top level containing tthree submodules: (I) Complete EIM interface in a submodule including all clock implementation (PLL, DCMs etc as neededed) with bclk at 133 MHz. The internal interface is a memory like interface like this: output wire clk133, output wire cs, output wire we, output wire [xy : 0] address, output wire [31 : 0] write_data, input wire [31 : 0] read_data, This interface would be running at 133 MHz in phase with bclk (it would be bclk) (II) A cryptech_system module that accepts an interface like the one from EIM (switch input/output) and also the system_clk and reset. This module would contain a submoudle that implements the clock domain crossing logic (built using fifos). It would also contain an example design - bram + simple adder logic. (III) A module that implements the reset and clocking needed. Basically the module I have today in my baseline. The clk50 would be connected to system_clk in (II). (2) fpga_setup (I prefer eim_setup because that is what the code does, but what the heck.) SW. Sound great that you have a clean version of this. (3) Simple test SW that uses the bram and adder logic and hopefully don't bump into any read/write errors. Does this match what you are proposing? If so, yes I would very much have that done. Having it next week would be great!
