For certain Intel devices, specify the I/O standard type for an I/O pad in the design with the I/O Standard panel in the Synplify SCOPE window.

The Synplify SDC syntax for the define_io_standard constraint, in which the delay_type must be either input_delay or output_delay.

define_io_standard Constraint

define_io_standard [–disable|–enable] {<objectName>} -delay_type \
[input_delay|output_delay] <columnTclName>{<value>} [<columnTclName>{<value>}...]

For details about supported I/O standards, refer to the Synopsys FPGA Synthesis Reference Manual.
