More consistent indentation and section headings.
Convert yoscrypt blocks to lists of cmdrefs (so they link to the commands in question).
Also update said lists.
Add other common optimizations/mapping commands.
Remove example synth script in favour of the examples on the next page.
Renamed python script so that it sits next to the testbench file when alphabetically sorted.
Reverted `MAX_WIDTH` to full precision for truncation testing.
Expected values are now stored in full precision rather than truncating to the same value as the input.
i.e. 0x5a5a5a5a will truncate to 0x5a5a for write data but will remain 0x5a5a5a5a for expected read.
Adds TDP submodule to generator.
Adds shorthand expected signal to testbench (mostly to make it easier when I look at the vcd dump to figure out what I did wrong in tests).
Adds `double_sync_ram_sdp` to `common/blockram.v`, providing a test for two disjoint memories.
Refactor python blockram template to take a list of params to support the above.
Also change the smaller single TDP36K tests to also test `port_a_width` value.
Use python script to generate tests for both SDP and TDP across multiple sizes of RAM.
Adds sync_ram_sdp_(wwr|wrr) to common blockram.v for double width write and double width read respectively.
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.
In preparation for substantial expansion of CXXRTL's runtime, this commit
reorganizes the files used by the implementation. Only minimal changes are
required in a consumer.
First, change:
-I$(yosys-config --datdir)/include
to:
-I$(yosys-config --datdir)/include/backends/cxxrtl/runtime
Second, change:
#include <backends/cxxrtl/cxxrtl.h>
to:
#include <cxxrtl/cxxrtl.h>
(and do the same for cxxrtl_vcd.h, etc.)
