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

Pin Planner assignment Problem solved...

a) Realization: Pin Planner is nothing more than a viewer for end results.

b) The correct format of the Tcl, despite the example from

[Tcl_Console]>help -examples

is as follows. (PIN_name followed by SIGNAL_name)

-----snippet------------# QuartusII>View>Utilty_windows>tcl_console# >source maestro_pin.tcl# Assignment Editor will show# To AssignmentName Value Enabled# debug_spi_sclk_0 Location PIN_B12 Yes

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

Notes:

1. The Assignment editor shows a check mark on each row no matter what nonsense text the Tcl script enters.

2. QuartusII>Project>Generate_Tcl_file_for_project is handy to capture any manual mods made in Assignment Editor.
