| | | | | | | | | | | | This enables the usage of declarations of wand or wor with a base type of logic, integer, or a typename. Note that declarations of nets with 2-state base types is still permitted, in violation of the spec.
* | verilog: fix multiple AST_PREFIX scope resolution issuesZachary Snow2021-09-214-4/+110
|/ | | | | | | | - Root AST_PREFIX nodes are now subject to genblk expansion to allow them to refer to a locally-visible generate block - Part selects on AST_PREFIX member leafs can now refer to generate block items (previously would not resolve and raise an error) - Add source location information to AST_PREFIX nodes

|/ | | | | | | backends/protobuf/protobuf.cc depends on the source and header files generated by protoc, but this dependency wasn't explicitly declared. Add a rule to the Makefile to fix intermittent build failures when the protobuf header/source file isn't built before protobuf.cc.

* sv: support declaration in generate for initializationZachary Snow2021-08-319-1/+209
| | | | | | | | This is accomplished by generating a unique name for the genvar, renaming references to the genvar only in the loop's initialization, guard, and incrementation, and finally adding a localparam inside the loop body with the original name so that the genvar can be shadowed as expected.

* opt_merge: Remove and reinsert init when connecting nets.Marcelina Kościelnicka2021-08-221-3/+4
| | | | | | | | Mutating the SigMap by adding a new connection will throw off FfInitVals index. Work around this by removing the relevant init values from index whenever we connect nets, then re-add the new init value. Should fix #2920.
* opt_clean: Make the init attribute follow the FF's Q.Marcelina Kościelnicka2021-08-222-2/+26
| | | | | | | | | | Previously, opt_clean would reconnect all ports (including FF Q ports) to a "canonical" SigBit chosen by complex rules, but would leave the init attribute on the old wire. This change applies the same canonicalization rules to the init attributes, ensuring that init moves to wherever the Q port moved. Part of another jab at #2920.

* Generate an RTLIL representation of bind constructsRupert Swarbrick2021-08-1311-3/+312
| | | | | | | | | | | | | | | | | | | | | | | | | This code now takes the AST nodes of type AST_BIND and generates a representation in the RTLIL for them. This is a little tricky, because a binding of the form: bind baz foo_t foo_i (.arg (1 + bar)); means "make an instance of foo_t called foo_i, instantiate it inside baz and connect the port arg to the result of the expression 1+bar". Of course, 1+bar needs a cell for the addition. Where should that cell live? With this patch, the Binding structure that represents the construct is itself an AST::AstModule module. This lets us put the adder cell inside it. We'll pull the contents out and plonk them into 'baz' when we actually do the binding operation as part of the hierarchy pass. Of course, we don't want RTLIL::Binding to contain an AST::AstModule (since kernel code shouldn't depend on a frontend), so we define RTLIL::Binding as an abstract base class and put the AST-specific code into an AST::Binding subclass. This is analogous to the AST::AstModule class.
