Does SignalTap work with other ICs in the JTAG chain?

Does Quartus II SignalTap work with ICs in the JTAG chain other than the Altera FPGA where SignalTap is being utilized? I get "Invalid JTAG configuration" in the SignalTap II Logic Analyzer stp wind...

No. Signal Tap is an Intel FPGA only feature. It has to be included in a design in an Intel FPGA to connect to the device.

I'll try to be more clear. I want to use SignalTap II in an Altera FPGA but there is another IC in the JTAG chain with the FPGA. I'm not trying to use SignalTap on the non-Altera device. My question is can Quartus orchestrate JTAG to pass through the other device and make SignalTap work in the Altera device?

Thanks
