Description

Create a new pin to add to an IP integrator hierarchical module.

This command returns the name of the newly created pin object, or returns an error message if it failed.

Arguments

-from <arg> - (Optional) The starting index of a standard bus pin. This is unspecified for single bit pins.

-to <arg> - (Optional) The ending index of a standard bus pin. This is unspecified for single bit pins.

-dir [ I | O | IO ] - (Required) The direction of the pin. Valid values are I for input, O for output, and IO for bidirectional pins.

-type <arg> - (Optional) Defines the type of the pin as a clock pin (CLK), a reset pin (RST), a clock enable pin (CE), an interrupt pin (INTR), or as a data pin (DATA). If you do not define the pin type, it will be undefined (UNDEF).

-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.

<name> - (Required) The name of the subsystem pin to create. The name is referenced from the hierarchical module that the pin is being added to: /modName/pinname.

Examples

The following example creates a new input pin on the specified module in the current IP integrator subsystem design:

create_bd_pin -dir I -type rst /newMod1/rst
/newMod1/rst
