I continue to search for ideas that are close to the BitGrid, and I've come across Amir Hersch's mention of the need for a "spreadsheet iterator" in his blog post titled "More versus Faster"... the BitGrid would be a good spreadsheet iterator.
I'm still trying to figure out the cost/benefit ratio of getting rid of all routing in an a real world FPGA device. As an abstraction tool, it's totally cool and cost effective, as there are no static or dynamic power costs in a thought experiment. 8)
As an intermediate stage of compiling a design, there are time costs in translations, but they might be worth it when it comes to the ability to move elements of a system design orthogonal to other design decisions.
Time and persistent effort to get the questions answered will tell. I'm glad I'm still asking questions and pursuing the goal of getting a BitGrid chip built
Oh... another linguistic hit "hardware spreadsheet" as mentioned here.
