Emil J. Tywoniak 785bd44da7 rtlil: represent Const strings as std::string 2024-10-14 06:28:12 +02:00
Martin Povišer 9018d06a33 quicklogic: Avoid carry chains in division mapping 
The default mapping rules for division-like operations (div/divfloor/
mod/modfloor) invoke subtractions which can get mapped to carry chains
in FPGA flows. Optimizations across carry chains are weak, so in
practice this ends up too costly compared to implementing the division
purely in soft logic.

For this reason arrange for `techmap.v` ignoring division operations
under `-D NODIV`, and use this mode in `synth_quicklogic` to avoid carry
chains for divisions.

Martin Povišer 16ea497d7c pmgen: Have a single make pattern 
Remove duplicate %.pmg -> %_pm.h pattern. One of the duplicates overrode
the other, and in some conditions there were build races as to whether
the target directory for the generated header would exist. Instead have
a single rule which is properly generalized.

Martin Povišer 7d738b07da ql_dsp_*: Clean up 
Clean up the code up to Yosys standards. Drop detection of
QL_DSP2_MULTADD in io_regs since those cells can't be inferred with
the current flow anyway.

KrystalDelusion 9465b2af95 Fitting help messages to 80 character width 
Uses the regex below to search (using vscode):
	^\t\tlog\("(.{10,}(?<!\\n)|.{81,}\\n)"\);

Finds any log messages double indented (which help messages are)
and checks if *either* there are is no newline character at the end,
*or* the number of characters before the newline is more than 80.
