From e48013c649c141d73aa249d47865813379201f9e Mon Sep 17 00:00:00 2001 From: Rob Taylor Date: Mon, 1 Dec 2025 20:03:22 +0000 Subject: [PATCH 1/6] Add support for hierarchical module instantiation syntax MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This adds parsing and HIR support for Verilog-A module instantiation syntax: module_name #(.param(value)) instance_name (port1, port2); This syntax is used in some foundry PDK models (e.g., GF130 ESD models) to instantiate primitive modules like resistors and capacitors with parameter overrides. Changes: - Add ModuleInst grammar to veriloga.ungram with ParamAssignments and PortConnections - Implement parser grammar with lookahead to distinguish module instantiation from net declarations - Add ModuleInstItem HIR type to store instance name, module type, parameter assignments, and port connections - Add HIR lowering for module instances - Module instances are recorded but don't participate in name resolution (they will be processed during elaboration/flattening) Note: This is parsing support only. The actual instantiation/flattening of modules is not implemented - the instances are simply stored in the HIR for potential future use. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- integration_tests/MODULE_INST/module_inst.va | 35 +++++ openvaf/hir_def/src/item_tree.rs | 24 ++- openvaf/hir_def/src/item_tree/lower.rs | 60 ++++++- openvaf/hir_def/src/item_tree/pretty.rs | 11 ++ openvaf/hir_def/src/nameres/collect.rs | 4 + openvaf/parser/src/grammar/items/module.rs | 96 +++++++++++- openvaf/syntax/src/ast/generated/nodes.rs | 146 +++++++++++++++++- openvaf/syntax/veriloga.ungram | 18 +++ .../test_data/item_tree/module_inst.def_map | 13 ++ .../test_data/item_tree/module_inst.item_tree | 9 ++ openvaf/test_data/item_tree/module_inst.va | 15 ++ openvaf/tokens/src/parser/generated.rs | 5 + sourcegen/src/ast/src.rs | 5 + 13 files changed, 436 insertions(+), 5 deletions(-) create mode 100644 integration_tests/MODULE_INST/module_inst.va create mode 100644 openvaf/test_data/item_tree/module_inst.def_map create mode 100644 openvaf/test_data/item_tree/module_inst.item_tree create mode 100644 openvaf/test_data/item_tree/module_inst.va diff --git a/integration_tests/MODULE_INST/module_inst.va b/integration_tests/MODULE_INST/module_inst.va new file mode 100644 index 000000000..d628075df --- /dev/null +++ b/integration_tests/MODULE_INST/module_inst.va @@ -0,0 +1,35 @@ +// Test module instantiation syntax support +// This tests hierarchical module instantiation with parameter overrides + +`include "constants.vams" +`include "disciplines.vams" + +// Simple resistor module that can be instantiated +module resistor(p, n); + inout p, n; + electrical p, n; + parameter real r = 1.0 from (0:inf); + + analog begin + I(p, n) <+ V(p, n) / r; + end +endmodule + +// Module that instantiates resistors +module module_inst(d, s); + inout d, s; + electrical d, s, mid; + + parameter real rwire = 1e-3 from (0:inf); + parameter real rload = 1e3 from (0:inf); + + // Module instantiation with parameter override + resistor #(.r(rwire)) r_wire (d, mid); + resistor #(.r(rload)) r_load (mid, s); + + // Additional behavior + analog begin + // Add small leakage current + I(d, s) <+ V(d, s) * 1e-12; + end +endmodule diff --git a/openvaf/hir_def/src/item_tree.rs b/openvaf/hir_def/src/item_tree.rs index b40a07c4a..8ceb36137 100644 --- a/openvaf/hir_def/src/item_tree.rs +++ b/openvaf/hir_def/src/item_tree.rs @@ -73,6 +73,7 @@ impl ItemTree { ports, branches, functions, + module_insts, } = &mut self.data; modules.shrink_to_fit(); disciplines.shrink_to_fit(); @@ -87,6 +88,7 @@ impl ItemTree { functions.shrink_to_fit(); nature_attrs.shrink_to_fit(); discipline_attrs.shrink_to_fit(); + module_insts.shrink_to_fit(); } pub fn block_scope(&self, block: AstId) -> &Block { @@ -109,6 +111,7 @@ pub struct ItemTreeData { pub ports: Arena, pub branches: Arena, pub functions: Arena, + pub module_insts: Arena, } /// Trait implemented by all item nodes in the item tree. @@ -230,6 +233,7 @@ item_tree_nodes! { Function in functions -> ast::Function, NatureAttr in nature_attrs -> ast::NatureAttr, DisciplineAttr in discipline_attrs -> ast::DisciplineAttr, + ModuleInstItem in module_insts -> ast::ModuleInst, } #[derive(Debug, Eq, PartialEq, Clone)] @@ -250,6 +254,7 @@ pub enum ModuleItem { Branch(ItemTreeId), Node(LocalNodeId), Function(ItemTreeId), + ModuleInst(ItemTreeId), } impl_from_typed!
