Exporting RTL - Synthesized Design Checkpoint

The synthezised design checkpoint option appears to be gone from the tool. The User Guides reads as if it still exists but the option is removed from the tool. Is there some way to re-enable it?

@jprice,

 

Are you saying that you dont find File-->write_checkpoint in Vivado after synthesis?

 

You need to open the synthesized design after synthesis to get this write_checkpoint enabled.

Syed

@syedz,

 

The option was under Export RTL -> Synthesized Design Checkpoint. However the Synthesized Checkpoint option is gone, just the IP Catalog/System Generator options remain.

Re: Exporting RTL - Synthesized Design Checkpoint

There are few things to check here:
1) Which version of the tool are you using?
I can see the option available in 2016.1 HLS installed on a Win 7 machine at my end.
2) Which device are you using?
From 2016.1 we are not supporting devices older than 7 series in HLS. For those devices you need to use 2015.4.

Debraj

Re: Exporting RTL - Synthesized Design Checkpoint

This issue was originally a license issue. I'm seeing this issue again in 2016.2 and I suspect it is also a license issue though I'm not sure where to check. I use this feature a lot with HLS, I'm not sure why it keeps vanishing.

 

On a related note: I attempted to target a Virtex 6 on 2015.4 but no parts are listed (this used to work). I know licensing surrounding HLS has recently changed, but I'm not sure what to look for. I'm fairly certain these two issues are related.
