	[I] Setup del HPS y SDRAM
	===

Luego de agregar el HPS a Platform Designer hay que ejecutar un script Tcl para
que Quartus agarre la config correcta de impedancias y más magia. Si se
sintetiza sin más acción entonces pasa esto:

	Error (174068): Output buffer atom "platform:plat|platform_hps_0:hps_0|platform_hps_0_hps_io:hps_io|platform_hps_0_hps_io_border:border|hps_sdram:hps_sdram_inst|hps_sdram_p0:p0|hps_sdram_p0_acv_hard_memphy:umemphy|hps_sdram_p0_acv_hard_io_pads:uio_pads|hps_sdram_p0_altdqdqs:dq_ddio[0].ubidir_dq_dqs|altdq_dqs2_acv_connect_to_hard_phy_cyclonev:altdq_dqs2_inst|obuf_os_bar_0" has port "PARALLELTERMINATIONCONTROL[8]" connected, but does not use calibrated on-chip termination

Tools > Tcl Scripts. There navigate through your QSys project, synthesis >
submodules folders, and there you should find a script whose name ends with
pin_assignments.tcl . Select that script, run it and try and compile the
project again

Nota: es *_pin_assignments.tcl y no ningún otro
