From b0bee396a8edec360616b68e97a3bd373b700b26 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marcelina=20Ko=C5=9Bcielnicka?= Date: Wed, 8 Apr 2020 21:42:50 +0200 Subject: Add new builtin FF types The new types include: - FFs with async reset and enable (`$adffe`, `$_DFFE_[NP][NP][01][NP]_`) - FFs with sync reset (`$sdff`, `$_SDFF_[NP][NP][01]_`) - FFs with sync reset and enable, reset priority (`$sdffs`, `$_SDFFE_[NP][NP][01][NP]_`) - FFs with sync reset and enable, enable priority (`$sdffce`, `$_SDFFCE_[NP][NP][01][NP]_`) - FFs with async reset, set, and enable (`$dffsre`, `$_DFFSRE_[NP][NP][NP][NP]_`) - latches with reset or set (`$adlatch`, `$_DLATCH_[NP][NP][01]_`) The new FF types are not actually used anywhere yet (this is left for future commits). --- kernel/celltypes.h | 40 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) (limited to 'kernel/celltypes.h') diff --git a/kernel/celltypes.h b/kernel/celltypes.h index db54436cb..12dea93b8 100644 --- a/kernel/celltypes.h +++ b/kernel/celltypes.h @@ -139,8 +139,14 @@ struct CellTypes setup_type(ID($dff), {ID::CLK, ID::D}, {ID::Q}); setup_type(ID($dffe), {ID::CLK, ID::EN, ID::D}, {ID::Q}); setup_type(ID($dffsr), {ID::CLK, ID::SET, ID::CLR, ID::D}, {ID::Q}); + setup_type(ID($dffsre), {ID::CLK, ID::SET, ID::CLR, ID::D, ID::E}, {ID::Q}); setup_type(ID($adff), {ID::CLK, ID::ARST, ID::D}, {ID::Q}); + setup_type(ID($adffe), {ID::CLK, ID::ARST, ID::D, ID::E}, {ID::Q}); + setup_type(ID($sdff), {ID::CLK, ID::SRST, ID::D}, {ID::Q}); + setup_type(ID($sdffe), {ID::CLK, ID::SRST, ID::D, ID::E}, {ID::Q}); + setup_type(ID($sdffce), {ID::CLK, ID::SRST, ID::D, ID::E}, {ID::Q}); setup_type(ID($dlatch), {ID::EN, ID::D}, {ID::Q}); + setup_type(ID($adlatch), {ID::EN, ID::D, ID::ARST}, {ID::Q}); setup_type(ID($dlatchsr), {ID::EN, ID::SET, ID::CLR, ID::D}, {ID::Q}); } @@ -208,14 +214,48 @@ struct CellTypes for (auto c3 : list_01) setup_type(stringf("$_DFF_%c%c%c_", c1, c2, c3), {ID::C, ID::R, ID::D}, {ID::Q}); + for (auto c1 : list_np) + for (auto c2 : list_np) + for (auto c3 : list_01) + for (auto c4 : list_np) + setup_type(stringf("$_DFFE_%c%c%c%c_", c1, c2, c3, c4), {ID::C, ID::R, ID::D, ID::E}, {ID::Q}); + for (auto c1 : list_np) for (auto c2 : list_np) for (auto c3 : list_np) setup_type(stringf("$_DFFSR_%c%c%c_", c1, c2, c3), {ID::C, ID::S, ID::R, ID::D}, {ID::Q}); + for (auto c1 : list_np) + for (auto c2 : list_np) + for (auto c3 : list_np) + for (auto c4 : list_np) + setup_type(stringf("$_DFFSRE_%c%c%c%c_", c1, c2, c3, c4), {ID::C, ID::S, ID::R, ID::D, ID::E}, {ID::Q}); + + for (auto c1 : list_np) + for (auto c2 : list_np) + for (auto c3 : list_01) + setup_type(stringf("$_SDFF_%c%c%c_", c1, c2, c3), {ID::C, ID::R, ID::D}, {ID::Q}); + + for (auto c1 : list_np) + for (auto c2 : list_np) + for (auto c3 : list_01) + for (auto c4 : list_np) + setup_type(stringf("$_SDFFE_%c%c%c%c_", c1, c2, c3, c4), {ID::C, ID::R, ID::D, ID::E}, {ID::Q}); + + for (auto c1 : list_np) + for (auto c2 : list_np) + for (auto c3 : list_01) + for (auto c4 : list_np) + setup_type(stringf("$_SDFFCE_%c%c%c%c_", c1, c2, c3, c4), {ID::C, ID::R, ID::D, ID::E}, {ID::Q}); + for (auto c1 : list_np) setup_type(stringf("$_DLATCH_%c_", c1), {ID::E, ID::D}, {ID::Q}); + for (auto c1 : list_np) + for (auto c2 : list_np) + for (auto c3 : list_01) + setup_type(stringf("$_DLATCH_%c%c%c_", c1, c2, c3), {ID::E, ID::R, ID::D}, {ID::Q}); + for (auto c1 : list_np) for (auto c2 : list_np) for (auto c3 : list_np) -- cgit v1.2.3
