can not select Artix-7 1.0V industrial device in Vivado 2018.3.1

跳至解决方案

hello, Sir,

 

We plan to use XC7A50T-1CSG325I, my Vivado version is 2018.3.1. in select device window, when I select I in the temperature drop down list, nothing displays. select All remaining, then the parts show up. my question is 

1. need upgrade Vivado to a newer version to get Artix-7 1.0V industrial device show up? if so which version .

2. or does the parts displayed when All remaining selected support both C and I? if so, this means I need set the operating temperature in the .XDC ? and could you please show me the command?

 

Thanks

robert

You don't have to set temp grade in XDC.

The "I", and "E" Temperature grades for some of the older devices are not available in the Vivado Part Selector.  You can select the "XC" device since the performance of the XC devices are the same for "I" and "E" for the 7-Series devices for the respective temperature ranges. 

  The reason why the Vivado Part Selector for 7-Series does not break out the individual temperature grades is due to the legacy parts available in ISE.   Some device families, such as "XQ" or "XA" devices, the "I" temperature grade is available, but this may not be the case for "XC" devices.  

The UltraScale and UltraScale+ devices do have the temperature grade in the Vivado Part Selector.  Devices introduced in Vivado later than the 7 series devices will show "I", "E" and "C" temperature grade parts separately in the part selection.

hi, Graces, 

thank you!  one more question, 

need I set the temperate range in .XDC (if so, which command)? or Viviao defaults to use the industrial grade range for the timing analysis?

 

Look forward to your reply, thank you again ~~

Robert
