Agilex 5 A5ED013B: No legal IOPLL placement with EMIF Calibration IP (Err 16234)

Attached: pj_test_minimal_repro.zip - the minimal project that reproduces the error.

Extract to a short path (e.g. C:\pj_test\) to avoid Windows path-length issues with Quartus's generated files, then open test_pll.qpf and run a full compile.

test_pll_top.vhd instantiates just two IPs: pll.ip (Intel IOPLL FPGA IP, dynamic reconfiguration via Calibration IP enabled) and EMIF.ip (EMIF Calibration IP, standalone-PLL mode), connected only through the pll_calbus / pll_calbus_readdata signals. No pin assignments are present - the Fitter error happens purely from that calbus connection between the two IPs.
