[J-core] Memory_fpga

I was wondering if someone could tell me the function of the memory_fpga.vhd module. I have almost been able to fully synthesize the entire SOC using Vivado, and the only thing that it's telling me right now is that I'm missing that file. However, I had diffed the two memory_fpga files produced from the make process of both the mimas_v2 and the microboard, though both files were extremely long there were only 4 lines different from the two. So I just wanted to know if there was a significant difference between the two, and is the memory_fpga file board specific at all. If it is then I will have to make one for the Kintex 7 KC705, if it's not then I will just use one of the two files.

Also, porting the core into Vivado gave an error of DRC 23-20 LUTLP-1, which is a combinatorial loop in some logic, there were 3 modules in particular, 2 in the decode_core and one in the datapath I believe. I was also wondering if the J2 was compatible with superH-2A architecture?

Thank you,

Santiago Gutierrez
