Dynamic Method Handling

This class handles dynamic methods through the method_missing method in the class HDLRuby::High::HScope_missing

        stmnt.execute(self.mode)
    end
    # puts "End TimeBlock"
end

#init_sim(systemT) ⇒ Object

Initialize the simulation for system +systemT+.

def init_sim(systemT)
    self.each_statement { |stmnt| stmnt.init_sim(systemT) }
end

#repeat(number = -1,, mode = nil, &ruby_block) ⇒ Object

Adds a loop until +delay+ statement in the block in +mode+ whose

loop content is built using +ruby_block+.

def repeat(delay, mode = nil, &ruby_block) Adds a +number+ times loop statement in the block in +mode+ whose loop content is built using +ruby_block+. NOTE: if +number+ is negative, the number of iteration is infinite.
