Description
Opens a new or existing I/O Pin Planning design.
Note: The design_mode property for the current source fileset must be defined as PinPlanning in order to open an I/O design. If not, you will get the following error:
ERROR: The design mode of 'sources_1' must be PinPlanning
Arguments
-name
<arg> - (Optional) The name of a new or existing I/O Pin Planning design.
-part
<arg> - (Optional) The Xilinx device to use when creating a new design. If the part is not specified the default part will be used.
-constrset
<arg> - (Optional) The name of the constraint fileset to use when opening an I/O design.
Note: The
-constrset
argument must refer to a constraint fileset that exists. It cannot be used to create a new fileset. Use create_fileset
for that purpose.-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.Examples
The following creates a new I/O design called myIO:
open_io_design -name myIO
Note: The default source set, constraint set, and part will be used in this case.
The following example opens an existing I/O design called myIO, and specifies the constraint set to be used:
open_io_design -name myIO -constrset topCon
