Description
A BEL_PIN is a pin or connection point on a BEL object.
The BEL_PIN is a device object, associated with netlist objects such as the PIN on a logic CELL, which is the connection point for the NET.
Related Objects
As seen in Figure 2-11, BEL_PIN objects are related to BEL and SITE device resources, and PIN and NET netlist objects. You can query the BEL_PINs of BELs, SITEs, PINs, or NETs by using a form of the following Tcl command:
get_bel_pins -of_objects [get_pins usbEngine0/usbEngineSRAM/Ram_reg_9/CLKARDCLK]
You can also query the SLRs, and TILEs that BEL_PINs are located in, or NODEs associated with the BEL_PIN:
get_slr -of_objects [get_bel_pins SLICE_X8Y176/D5LUT/WA5]
Properties
The properties on a BEL_PIN object include the following, with example values:
Property Type Read-only Visible Value
CLASS string true true bel_pin
DIRECTION enum true true IN
INDEX int true true 1
INDEX_IN_BEL int true true 1
INDEX_IN_BUS int true true 1023
INDEX_IN_ELEMENT int true true 1
INDEX_IN_TILE int true true 65535
IS_BAD bool true true 0
IS_BIDIR bool true true 0
IS_CLOCK bool true true 0
IS_DATA bool true true 0
IS_ENABLE bool true true 1
IS_INPUT bool true true 1
IS_OPTIONALLY_INVERTIBLE bool true false 0
IS_OUTPUT bool true true 0
IS_PART_OF_BUS bool true true 0
IS_RESET bool true true 0
IS_SET bool true true 0
IS_TEST bool true true 0
IS_USED bool true true 0
NAME string true true IOB_X0Y197/OUTBUF/TRI
SITE_ID int true true 188
SPEED_INDEX int true true 0
To report the properties for all the BEL_PINs on a specific BEL object, you can use the following FOREACH loop in the Vivado Design Suite Tcl shell or Tcl Console:
foreach x [get_bel_pins -of [get_bels <bel_name>]] {
puts "****************** $x *****************"
report_property -all $x
}
Where <bel_name> is the name of the BEL object to report.
