Description
A NODE is a device object used for routing connections, or NETs, on the AMD part. It is a collection of WIREs, spanning across multiple tiles, that are physically and electrically connected together. A NODE can connect to a single SITE_PIN, or connect to no pins, serving instead to simply carry NETs into, out of, or across the SITE. A NODE can connect to any number of PIPs, and can also be driven by a tie-off.
Related Objects
As seen in the figure above, NODE objects are related to SLRs, TILEs, NETs, SITE_PINs, WIREs, PIPs, and other NODEs. You can query the NODEs by using a form of the following Tcl command:
get_nodes -of_objects [get_nets cpuClk]
You can also query the SLRs, and TILEs that NODEs are located in, or PIPs, SITE_PINS, SPEED_MODELs, WIREs associated with specific NODEs:
get_slrs -of_objects [get_nodes LIOB33_SING_X0Y199/IOB_T_OUT0]Properties
The properties on a NODE object can be reported with a command such as the following:
report_property -all [lindex [get_nodes -filter {IS_COMPLETE}] 0]get_nodes Tcl command without -of_objects or a name delimiter to narrow the results
is not recommended.The properties include the following, with example values:
