# This file contains various constraints for your chip including the

# target clock period, the capacitive load of output pins, and any

# input/output delay constraints.

#

# This constraint sets the target clock period for the chip in

# nanoseconds. Note that the first parameter is the name of the clock

# signal in your verlog design. If you called it something different than

# clk you will need to change this. You should set this constraint

# carefully. If the period is unrealistically small then the tools will

# spend forever trying to meet timing and ultimately fail. If the period

# is too large the tools will have no trouble but you will get a very

# conservative implementation.

create_clock CLK -name ideal_clock1 -period 8.0

# This constrainst sets the load capacitance in picofarads of the

# output pins of your design. 4fF is reasonable if your design is

# driving another block of on-chip logic.

set_load -pin_load 0.004 [all_outputs]

# Encounter doesn't seem to have its own way to specify dont_touch

# so we must do it in the SDC file
