I'm now trying to constrain the inputs and outputs of my design and appended these lines:
# Constrain the input I/O path
set_input_delay -clock clk_1MHz -max 5 [all_inputs]
set_input_delay -clock clk_1MHz -min 0 [all_inputs]
# Constrain the output I/O path
set_output_delay -clock clk_1MHz -max 5 [all_outputs]
set_output_delay -clock clk_1MHz -min -1 [all_outputs]
5ns is the delay for the level shifters used on the in- and outputs of the design.
However I always get a setup violation?
Do you have an idea what I'm doing wrong?
PS: What should I do with 'altera_reserved_tck' which appears in my ReporT?
