Krystine Sherwin 0d1668c1ee QLF_TDP36K: asymmetric simulation tests 2023-12-04 15:52:03 +01:00
Krystine Sherwin 497cd021af QLF_TDP36K: truncation tests matter 
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.

Krystine Sherwin 7f12d0ba95 QLF_TDP36K: more basic tdp/sdp sim tests 
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).

Krystine Sherwin 3d08ed216d QLF_TDP36K: parameterised sim test gen 
Also limited to 16 tests per file to allow parallelism.
Previous tests are converted to new test format with no sim test steps.

Also both use the same named parameters for better mirroring.

Krystine Sherwin 7513bfcbfe quicklogic: fix double width read 2023-12-04 15:52:03 +01:00
Krystine Sherwin 8d3b238b9b quicklogic: Testing split TDP36K 
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.

Krystine Sherwin 991850e1c9 quicklogic: Initial blockram tests 
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.

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.

Catherine 62bbd086b1 cxxrtl: reorganize runtime component files. 
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.)

Catherine 3dd5262355 Add *.dwo files to .gitignore 
These files are generated in `-gsplit-dwarf` builds, which provide faster linking.

Generalize what was formerly the unsigned-only architecture to support
both signed and unsigned multiplication, use that as default, and set
aside the special low-power architecture that was formerly used for
signed multipliers.
