Document Table of Contents altera_chip_pin_lc

Use the altera_chip_pin_lc attribute to make pin assignments. This attribute applies a string value to inputs and outputs. Use the attribute only on the ports of the top-level entity in the design. Do not use this attribute to assign pin locations from entities at lower levels of the design hierarchy.
Note: The altera_chip_pin_lc attribute is not supported for any MAX series device.

In the SCOPE window, set the value of the altera_chip_pin_lc attribute to a pin number or a list of pin numbers.

You can use VHDL code for making location assignments for supported Intel devices. Pin location assignments for these devices are written to the output .tcl file.

Note: The data_out signal is a 4-bit signal; data_out[3] is assigned to pin 14 and data_out[0] is assigned to pin 15.
