Hi,
I try to design circuit that convert 10 bit binary to BCD with 74185 IC in Proteus, but when i run this project output of this IC like this attached picture is unknown(IC don't work!) and I did active enable. why? and how can give suitable output?

and i don't receive any error!

 

Silly question, but did you connect the ground and VCC to that chip in Proteus?

 

That chip is obsolete and expensive.

No.

thanks.

 

this is connected in proteus package for this component.

 

this is connected in proteus package for this component.

Connected to what?
It needs a power supply.

this IC connected in proteus package setting.

This post by @absf seems to imply that Proteus has 74185 for schematic capture, but not simulation.

This post shows EPROMs programmed to do the conversion.

 

I did a copy... Well its a hex file to be used in a gal16v8.. I have attached the jed file in the zip..

Here it is working

Does your version of Proteus have 74185 for schematic capture, but not simulation?

 

Okay, I'll byte.
Where is the power supply for that simulation.

 

@crutschow ISIS hides all power pins, by default they are connected to gnd and 5v
remember Proteus ISIS isn't really an analysis tool and digital simulation is fast because of this... I can run micro code at 100% up to nearly 32Mhz..
so a lot of the analogue simulation is replaced by simple digital pullup or pulldown.. If you want to simulate to component level then LTSpice or other should be used... In other words, "It works for me"..

@DL1234 Yes there is a component but no model attached.... I just used a GAL because I can... For simulation purposes it works fine..

 

and i don't receive any error!

At least two members have found that Proteus won't simulate 74185, so the easiest thing to do is to use a lookup table in a programmable device.

If the objective was to implement the converter, the algorithm is readily available.

That's the beauty of the GAL... Still available so you can still make the circuit I simulated.. The only thing I didn't include was the "G" input... Easily remedied...
