Well, I think it is a matter of negotiation between the VHDL-coders. Personally, I didn't like the agreement proposed by Tsujikawa. And there is another problem: my design methodology is based in "chip replacement", and Tsujikawa's methodology consists in "creating new boards". This method is much more difficult for debugging, and testing each "chip-replacement" becomes impossible, because they are not pin-compatible with the original ones.
If we can choose an standardized design methodology, I think we can exchange our codes. My VHDL coding-style is technology-independent, which means that one can use it for implementing in Xilinx FPGAs, in Altera FPGAs, and also for ASIC fabrication. AFAIK, as I saw in Kunihiko's VDP code, I could not connect it directly in place of the original VDP.
