Where can I find BSDL files for Synergy MCUs?

BSLD files for Synergy MCUs can be found on the Downloads Tab from the MCU web page. For example, the web page for the S7G2 is located here: 

https://www.renesas.com/produc...7-series.html

Note that you can select IBIS/BSLD to search for just those file types.
