[myhdl-list] Driving constants

[Sébastien B. <seb...@mi...>]

Hi,

I need to create instances that only drive their output to some constant 
level, e.g. the equivalent of:

module foo(output bar);
assign bar = 1'b1;
endmodule

I have tried doing:
	def ImplementControl(self):
		@always_comb
		def logic():
			self.control.ack_o.next[0] = 1
		return logic

but MyHDL doesn't cope with the empty sensitivity list.

Setting the value at signal creation (e.g. things like 
self.control.ack_o = Signal(intbv(1))) is not an option because it would 
become very messy with my object-oriented approach. Besides, I would 
find it surprising that describing something as basic as a constant 
driver is an intractable problem in MyHDL.

Any solutions?

Thanks,
Sébastien
