Function documentation

TextLocation slang::netlist::NetlistBuilder::toTextLocation(SourceLocation loc) const

Convert a slang SourceLocation to a TextLocation using the compilation's SourceManager and the graph's FileTable.

void slang::netlist::NetlistBuilder::build(const ast::Symbol& root, bool parallel = true, unsigned numThreads = 0)

Build the netlist graph from the given root symbol using a two-phase collect-then-dispatch approach. Phase 1 visits the AST sequentially to create ports, variables, and instance structure. Phase 2 dispatches deferred DFA work items in parallel (when parallel=true and threads are available). numThreads specifies the thread pool size; 0 means use hardware concurrency.

DriverList slang::netlist::NetlistBuilder::getDrivers(ast::ValueSymbol const& symbol, DriverBitRange bounds) const

Get a list of all the drivers for the given symbol and bit range. If there are no drivers, the returned list will be empty.
