From 1070f2e90b9ba37856932189ef09a0f2316d9a21 Mon Sep 17 00:00:00 2001 From: SergeyDegtyar Date: Mon, 23 Sep 2019 15:51:41 +0300 Subject: [PATCH] Add new tests for Efinix architecture. Problems/questions: - fsm.ys. equiv_opt -assert failed because of unproven cells; - latches.ys,tribuf.ys - internal cells present; - memory.ys - sat called with -verify and proof did fail. --- Makefile | 1 + tests/efinix/.gitignore | 3 ++ tests/efinix/add_sub.v | 13 +++++ tests/efinix/add_sub.ys | 9 ++++ tests/efinix/adffs.v | 87 ++++++++++++++++++++++++++++++++++ tests/efinix/adffs.ys | 12 +++++ tests/efinix/alu.v | 19 ++++++++ tests/efinix/alu.ys | 13 +++++ tests/efinix/counter.v | 17 +++++++ tests/efinix/counter.ys | 12 +++++ tests/efinix/dffs.v | 37 +++++++++++++++ tests/efinix/dffs.ys | 12 +++++ tests/efinix/div_mod.v | 13 +++++ tests/efinix/div_mod.ys | 10 ++++ tests/efinix/fsm.v | 73 ++++++++++++++++++++++++++++ tests/efinix/fsm.ys | 14 ++++++ tests/efinix/latches.v | 58 +++++++++++++++++++++++ tests/efinix/latches.ys | 20 ++++++++ tests/efinix/logic.v | 18 +++++++ tests/efinix/logic.ys | 8 ++++ tests/efinix/memory.v | 21 ++++++++ tests/efinix/memory.ys | 18 +++++++ tests/efinix/mul.v | 11 +++++ tests/efinix/mul.ys | 9 ++++ tests/efinix/mux.v | 100 +++++++++++++++++++++++++++++++++++++++ tests/efinix/mux.ys | 8 ++++ tests/efinix/run-test.sh | 20 ++++++++ tests/efinix/shifter.v | 22 +++++++++ tests/efinix/shifter.ys | 11 +++++ tests/efinix/tribuf.v | 29 ++++++++++++ tests/efinix/tribuf.ys | 12 +++++ 31 files changed, 710 insertions(+) create mode 100644 tests/efinix/.gitignore create mode 100644 tests/efinix/add_sub.v create mode 100644 tests/efinix/add_sub.ys create mode 100644 tests/efinix/adffs.v create mode 100644 tests/efinix/adffs.ys create mode 100644 tests/efinix/alu.v create mode 100644 tests/efinix/alu.ys create mode 100644 tests/efinix/counter.v create mode 100644 tests/efinix/counter.ys create mode 100644 tests/efinix/dffs.v create mode 100644 tests/efinix/dffs.ys create mode 100644 tests/efinix/div_mod.v create mode 100644 tests/efinix/div_mod.ys create mode 100644 tests/efinix/fsm.v create mode 100644 tests/efinix/fsm.ys create mode 100644 tests/efinix/latches.v create mode 100644 tests/efinix/latches.ys create mode 100644 tests/efinix/logic.v create mode 100644 tests/efinix/logic.ys create mode 100644 tests/efinix/memory.v create mode 100644 tests/efinix/memory.ys create mode 100644 tests/efinix/mul.v create mode 100644 tests/efinix/mul.ys create mode 100644 tests/efinix/mux.v create mode 100644 tests/efinix/mux.ys create mode 100755 tests/efinix/run-test.sh create mode 100644 tests/efinix/shifter.v create mode 100644 tests/efinix/shifter.ys create mode 100644 tests/efinix/tribuf.v create mode 100644 tests/efinix/tribuf.ys diff --git a/Makefile b/Makefile index 2cac80f0f..1be01a86c 100644 --- a/Makefile +++ b/Makefile @@ -710,6 +710,7 @@ test: $(TARGETS) $(EXTRA_TARGETS) +cd tests/aiger && bash run-test.sh $(ABCOPT) +cd tests/arch && bash run-test.sh +cd tests/ice40 && bash run-test.sh $(SEEDOPT) + +cd tests/efinix && bash run-test.sh $(SEEDOPT) @echo "" @echo " Passed \"make test\"." @echo "" diff --git a/tests/efinix/.gitignore b/tests/efinix/.gitignore new file mode 100644 index 000000000..b48f808a1 --- /dev/null +++ b/tests/efinix/.gitignore @@ -0,0 +1,3 @@ +/*.log +/*.out +/run-test.mk diff --git a/tests/efinix/add_sub.v b/tests/efinix/add_sub.v new file mode 100644 index 000000000..177c32e30 --- /dev/null +++ b/tests/efinix/add_sub.v @@ -0,0 +1,13 @@ +module top +( + input [3:0] x, + input [3:0] y, + + output [3:0] A, + output [3:0] B + );
