Sorry I was agitated and I put my questions in an offensive way; my apologies.
But for me it is very hard to understand the fundamental difference between a SRAM based FPGA and a Flash or anti-fuse based FPGA.
The difference is that the FPGA performs a program in LUT, and Hardcopy has direct wire connection.
FPGA is commodity hardware.
And the same chip today may be the Amiga, c64 tomorrow and the day after the dishwasher controller.
Depending on what software it is loaded into it.
This is the same situation as with an ordinary PC running an emulator.
