AXI Quad SPI V3.2 - Slave Select toggles at the end of the transaction


In the Quad SPI version 3.2 core, the Slave select toggles at the end of the transaction. The work-around to avoid the slave select toggle is to use manual slave selection mode.

Is there an automatic slave selection mode available?


A patch is attached to this Answer Record for Vivado 2016.4 which adds automatic slave selection mode.

Please read the text file present under patch_readme for notes on using the patch.

The IP RTL will be changed in Vivado 2017.1 so no patch will be required.
