With RTL on the iCE40

The wafer names IOB_6a, IOT_8b… as well as the pin number ICE_2, ICE_3, ICE_4… can be used from the RTL by picking them from this PCF file.

For Amaranth, until this gets upstreamed, the various board resources including its pins are defined on

With code on the RP2040

The FPGA pins and other signals are defined in pico_ice.h.

The PMOD pins can also be accessed from pmod.h and ice_pmod.h.
