Create a block from topblock

Hi everyone

I’m just trying to make an autocorrelation block. I made the calculation
of this one on GRC which generate a topblock.
And I would like to know how to make a block from this topblock…
I have also created the xml file of this block.
So is it possible, and how can I install it in gnuradio companion?

Thank you

Hey Martin,
There is a facility to create a hierarchial block using the GNU radio
companion as far as I learnt from the GNU radio site. You can straight
away add those blocks to your companion by just executing the flowgraph.
Please ignore my reply, if it isn’t relevant to your query.
