## Using eclipse to run the software and debug it
You can use the eclipse + zilin embedded CDT plugin to do it.
You can use the eclipse + zilin embedded CDT plugin to do it (http://opensource.zylin.com/embeddedcdt.html). Tested with Helios Service Release 2 and the corresponding zylin plugin.
## Briey SoC
As a demonstrator, a SoC named Briey is implemented in src/main/scala/VexRiscv/demo/Briey.scala. This SoC is very similar to the Pinsec one :
