Pin Planner: Can't edit the current device because the device is read-only

Dave,

Thanks, I right away learnt two things from your post

a) Search on "pin assignment: not "pin planner"

b) Tcl is the way to go.

I'm not quite there but I'm close:

Tcl prompt....QuartusII>View>Utility_windows>Tcl_console

Tcl script.....>source myscript.tcl

After running myscript.tcl and compiling my VHDL I can see

a) Under QuartusII>Assignment_editor that all my pin locations were accepted correctly and without complaint.

b) Under Pin Planner I see every pin assignment in the assignment editor was ignored.

---snippet---------# QuartusII>View>Utilty_windows>tcl_console# >source maestro_pin.tcl# set_global_assignment -name family CYCLONE V# set_global_assignment -name device 5CGXFC7C7F23C8

set_location_assignment -to PIN_b12 debug_spi_sclk_0

set_location_assignment -to PIN_f12 debug_spi_syn_n_0

set_location_assignment -to PIN_c18 fpga_usb_uart_cts

etc...

---end snippet---------

Some things that don't work...

1. despite Altera documentation of the tcl console saying otherwise

>quartus_sh -t myfile.tcl

does not work

2. the .qsf file QuickScriptEditor...no hits when search its help for "Pin" or "assignment". Search on "the" was sucessful :). Conclusion=.qsf files editor won't help me.
