Adding Reactivity

• Use class scenic_process for synthesizable modules

• Add clock(s)

• Divide operations across cycles using next()

  • BC restrictions: loops, ‘balanced’ branches

• Distinguish expression types

  • expr and lambda-expr are syntactically different
  • lambda-expr are delay evaluated

• wait_until and watching

  • use only lambda-expr
  • use expr in control flow
  • watching declared in process instatiation
  • Example:
