Why the Triple rate SDI TX and SD-SDI TX can’t fit into the same Quad in Stratix II device?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

You might receive the following error when fit the Triple Rate SDI TX and SD-SDI Tx into the same Quad.

Error (164061): Can't place GXB Central Control Unit "SDI_Instance:inst3|sdi_megacore_top:sdi_megacore_top_inst|sdi_txrx_port:sdi_txrx_port_gen[0].u_txrx_port|rc_gxb_tx:gen_tx_alt2gxb.u_gxb|alt2gxb:alt2gxb_component|channel_quad[0].cent_unit" in target device because of its constraints

The fitter report an error because logical PLL number for both instance PLLs are the same, and this happens when we have DPRIO enable. However the SD-SDI instance has pll cascading enable. The input of this pll has to be fed by pll of triple rate SDI.

Resolution Please create a quartus.ini file in your project directory and include the following setting. farm_s2gx_dprio_bypass_pll_number_check=on
