I want to know the max speed of NIOS ii based on cyclone iii EP3C120N780C

After running the Read SDC, I noticed that somehow it creates the altera_reserved_clk with the same name, altera_reserved_clk, This can be seen by Running "Report Clocks" on the Diagnostic section.

There fore I uncoment the generation of the clock from the template,

and change the references from tck to altera_reserved_tck.

# create_clock -name tck -period __period [get_ports altera_reserved_tck]# Cut all paths to and from tck

set_clock_groups -asynchronous -group [get_clocks altera_reserved_tck]# Constrain the TDI port

set_input_delay -clock altera_reserved_tck -clock_fall 20 [get_ports altera_reserved_tdi]# Constrain the TMS port

set_input_delay -clock altera_reserved_tck -clock_fall 20 [get_ports altera_reserved_tms]# Constrain the TDO port

set_output_delay -clock altera_reserved_tck -clock_fall 20 [get_ports altera_reserved_tdo]

This is at least constraining the altera paths, however I am not tottally sure if this is correctly contrained, I would like to know if it is correct.

I hope someone find this usefull.

Thankyou
