Vivado - block diagram - add a combinatorial gate

Jump to solution

is there a way to add a simple 'AND' gate (or any other gate) to the Vivado block diagram, for example to and the peripheral_aresetn signal with an AXI_GPIO signal?

 

I need to manually control the reset of an axis_data_fifo, but I also prefer to have it reset by the 'regular' peripheral_aresetn signal too, so a simple AND gate would suit this need.

Hi,

 

You can use Utility Vector Logic IP and configure it for AND gate operation

ok thanks - that works fine!

 

2 remarks though :

 

* didn't find it because of the strange name I guess

* also : I cannot find it in the IP catalog ... I searched through it, but it doesn't come up if you type a part of the name in the IP catalog search bar. It only appears if you add IP to the block design ...

 

a logic place for this could be under the category 'Basic Elements' , where you can find registers, counters, ...?

@ronnywebers Utility Vector Logic IP can only be used in IP Integrator.

 

I think you are using old vivado version thats why you are not able to search the IP. From 2015.1 Vivado you can search the IP as seen in the screenshot you can only add it in IP Integrator

I'm using Vivado 2014.4, it's indeed not visible under the BaseIP section - see sreenshot

 

soon I will upgrade to 2015.1 - thanks for the info!
