bit-extender with 1 bit output

[logoliv]

For my actual project I made a subcircuit that is identical to a D Flip-Flop PRE/CLR (neg) but with an enable pin and parametrable bit width. It works fine but I can't use it with a 1 bit BW (the selection just doesn't work). I think the cause of the problem is the bit-extender component that don't accept 1 bit output (and that's logical for a bit extender) :

It would be helpful to make this component also accept 1 bit output : it's mandatory if we want to make generic designs that can accept a BW from 1 to 32 bits. Here is my circuit if you want to test by yourself.

You're right: The bit extender's current rule is that output bit width must be > than input bit width. Equal bit width is not accepted.

I don't see why equal size shouldn't be accepted. How urgent is this for you and your project (in terms of release date?)

[logoliv]

ASAP ? No just a joke :)

I've no "release date" yet, it's a middle term project I have as a hobby : I'm recreating the Z80 CPU from schematics I found for Altera Quartus... My turn to ask : what's your estimated release date for 1.14 milestone ?

I could make a separate 1 bit version (if I want to get rid of the tri-state buffer that I add for now before the clock pin of the standard library DFF). Just proposed that so Antares can have more generic components, usable in more situations.

Perhaps end of July. I'm glad you have a workaround.

Interesting, your project with the Z80! Keep asking for missing features if you get stuck, and I would love to see your project someday. Maybe you present it in the discussions once it has reached a level you're happy with :)

I will when it's finished, but there's still a long way until completion so it won't be tomorrow 😄 Thanks for your reactivity by the way !

@logoliv You're welcome. BTW you don't have to close issues when I've set the "done" label. I usually keep the open until I deploy the release they are targeted for. This way people see what's coming with the next release, which also leads to fewer duplicates.

OK I was asking myself 😃
