Function emit_wpe_user_project_testbench

    name: &str,

) -> String

The off-chip engine’s host testbench, driving wpe_user_project through its Caravel pins at the engine’s clock: the UART on the plan’s GPIOs, the part’s pin model on the PSRAM GPIOs (a pad driven exactly while its io_oeb is low), every PSRAM pin reaching the part pads after the macro drives it and the part’s data reaching io_in pads.in_ps after the part drives it, the management SoC’s clock and reset, and an idle Wishbone. A pin driven the wrong way at any point after reset fails the run with PIN-DIRECTION.
