PL initialization signals[edit | edit source]
This page provides information about the Programmable Logic (PL) initialization signals: PS_PROGRAM_B, PS_INIT_B, and PS_DONE.
Please refer to UltraScale Architecture PCB Design User Guide for more information about the usage and configuration of the initialization circuit and signals. As described in the link, the user can initialize the PL using these signals.
ONDA SOM signals are configured in the following way:
- PS_PROGRAM_B has an internal 4k7 Ω pull-up
- PS_INIT_B has an internal 4k7 Ω pull-up
- PS_DONE has an internal 4k7 Ω pull-up. It does not require any external pull-up or pull-down but can be used for connecting a user led for a configuration completed indication (see for example ONDA EVK schematics).
