In rtl/hub75_framebuffer.v it uses SB_SPRAM256KA which are memory specific to the ice40up5k. You can replace this whole module with just inferred RAM.

And in rtl/hub75_phy.v and rtl/hub75_phy_ddr.v it uses SB_IO which are used for IO registers and will need to be replaced with equivalent on your chosen architecture.

hello, i am not so familiar with FPGA, could you show me the replacement module on Cyclone platform if you have some experiences.
