PSoC™ Creator & Designer

Anonymous
Not applicable

Hi all,

   

I wish to be able to modify a single bit within a bus from the Fabric using a PSoC4.

   

I found this post which (partly) answered my question : http://www.cypress.com/comment/142141#comment-142141

   

The problem is: the design won't generate with the attached schematic. You can notice I purposefully disconnected the wire [0], which goes through the OR gate.

   

The error code is: "Multiple drivers on signal "Net_43", bit(s) "0"."

   

 

   

Any idea on how to solve this?

   

Thanks!

   

Romain

RomainF,

   

you can insert a "dummy" component to cheat the fitter. See example below which uses custom BusConnect component to do this:

Hi, thanks for the tip!

   

Basically I'd like this bit to be dependent on other logic. I managed to merge the bit [0] with a constant for the other bits [7:1].
That should do it for now for my use case. (see first image)

   

   

 

   

I tried to replicate this with a 2:1 mux without success. See second image below.

        Since you do not need full featured BusConnect component, I made small Dummy component specifically for resolving routing issues: http://www.cypress.com/forum/psoc-community-components/dummy-empty-component-digital-bus-routing
