- Log message:
- The patch introduces a new configuration option `A23_RAM_REGISTER_BANK,
which controls instantiation of Amber 23 register bank.
If the option is set, a ram-based variant of the register bank is instantiated.
It can be useful in low-end FPGA designs, where flipflops and muxes are costly.
Altera Cyclone III resource utilization:
- flipflop-based register bank: 1583 combinationals + 856 registers
- ram-based register bank: 268 combinationals + 156 registers
