Why does the F-Tile HDMI FPGA IP Design Example fail to migrate from the Quartus® Prime Pro Edition Software version 23.3 to 23.4?

Due to a problem in the Quartus® Prime Pro Edition Software version 23.3 to 23.4,  the HDMI 2.1 RX-TX retransmit Design Example on clocked video interface fails to compile after performing IP upgrade.

The following error message will appear:

Error(23035): Tcl error: couldn't open "../rtl/gxb/rx_phy/rx_phy_12g/sim/rx_phy_12g.v ../rtl/gxb/rx_phy/rx_phy_12g/synth/rx_phy_12g.v": no such file or directory...

To work around this problem, the below modification is required to the rtl/ipgen.tcl file:

• 1. set rx_phy_12G_files [glob ../rtl/gxb/*/*/synth/rx_phy_12g.v]
• 2. set tx_phy_12G_files [glob ../rtl/gxb/*/*/synth/tx_phy_12g.v]

This problem is fixed beginning with the Quartus® Prime Pro Edition Software version 24.1.
