Struct SynthesisPapercut

pub struct SynthesisPapercut { /* private fields */ }

Pass to check common synthesis issues.

1. If a memory is only read-from or written-to, synthesis tools will optimize it away. Add @external attribute to the cell definition to make it an interface memory.

Trait Implementations

impl ConstructVisitor for SynthesisPapercut

fn from(_ctx: &Context) -> CalyxResult<Self>

where Self: Sized,

Construct the visitor using information from the Context

fn clear_data(&mut self)

Clear the data stored in the visitor. Called before traversing the next component by [ir::traversal::Visitor].

fn get_opts(ctx: &Context) -> LinkedHashMap<&'static str, ParseVal>

where Self: Named,

impl Debug for SynthesisPapercut

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DiagnosticPass for SynthesisPapercut

fn diagnostics(&self) -> &DiagnosticContext

Return an iterator of the diagnostics gathered by this pass.

impl Named for SynthesisPapercut

fn name() -> &'static str

The name of a pass. Is used for identifying passes.

fn description() -> &'static str

A short description of the pass.

fn opts() -> Vec<PassOpt>

Set of options that can be passed to the pass. The options contains a tuple of the option name and a description.

impl Visitor for SynthesisPapercut

fn start( &mut self, comp: &mut Component, _ctx: &LibrarySignatures, _comps: &[Component], ) -> VisResult

Executed before the traversal begins.

fn precondition(_ctx: &Context) -> Option<String>

where Self: Sized,

Precondition for this pass to run on the program. If this function returns None, the pass triggers. Otherwise it aborts and logs the string as the reason.

fn start_context(&mut self, _ctx: &mut Context) -> VisResult

Transform the ir::Context before visiting the components.

fn finish_context(&mut self, _ctx: &mut Context) -> VisResult

Transform the ir::Context after visiting the components.

fn iteration_order() -> Order

where Self: Sized,

Define the iteration order in which components should be visited

fn traverse_component( &mut self, comp: &mut Component, signatures: &LibrarySignatures, components: &[Component], ) -> CalyxResult<()>

where Self: Sized,

Define the traversal over a component. Calls Visitor::start, visits each control node, and finally calls Visitor::finish.

fn do_pass(&mut self, context: &mut Context) -> CalyxResult<()>

where Self: Sized + ConstructVisitor + Named,

Run the visitor on a given program ir::Context. The function mutably borrows the control program in each component and traverses it.

fn do_pass_default(context: &mut Context) -> CalyxResult<Self>

where Self: ConstructVisitor + Sized + Named,

Build a Default implementation of this pass and call Visitor::do_pass using it.
