Why isn't the HPS_nRST(rst_pin_rst_n) driven LOW on cold reset?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

The Cyclone® V and Arria® V Handbooks incorrectly state that HPS_nRST will be driven on some cold resets.

 

  • The HPS_nRST (rst_pin_rst_n) signal is only driven on Warm resets. 
  • It is not driven on Cold or POR resets.
Resolution

This documentation problem will be fixed in a future release of the Cyclone V and Arria V Handbooks.
