Description

This Tcl command creates a link (or links) to a file/files in your project. Specify absolute or relative path and name of the file you want to link. The same file you cannot link to different libraries.

Arguments


Parameter	Type	Description
convert_EDN_to_HDL	boolean	Use the `-convert_EDN_to_HDL` parameter to convert the EDIF file to HDL and then import the converted HDL file. Valid values: TRUE, 1, true, FALSE, 0 or false. If the `–edif` option is not specified or the `-convert_EDN_to_HDL` is used with another option, EDIF to HDL conversion will fail.
hdl_source_folder	string	Name of the HDL folder you want to link. For unlink folder you must unlink files form folder one by one.
library	string	Specifies the name of the library where you want to link file. The same file you cannot link different libraries.
hdl_source	string	Name of the HDL file you want to link.
stimulus	string	Name of the stimulus file you want to link.
edif	string	Name of the EDIF Netlist file you want to link. It used with `convert_EDN_to_HDL` option.
sdc	string	Name of the SDC file you want to link.
ndc	string	Name of the NDC (Compile Netlist Constraint) file you want to link.
fp_pdc	string	Name of the Floor Planner PDC file you want to link.
io_pdc	string	Name of the IO PDC file you want to link.
net_fdc	string	Name of the FDC (Synplify Netlist Constraint) file you want to link.
vcd	string	Name of the VCD file you want to link.
verilog_netlist	string	Name of the VM (Synthesized Verilog Netlist) file you want to link.
pin	string	Name of the PIN file you want to link. (Not supported for PolarFire, SmartFusion 2, IGLOO 2, and RTG4 families).
dcf	string	Name of the DCF(Timing Constraint Files) file you want to link. (Not supported for PolarFire, SmartFusion 2, IGLOO 2, and RTG4 families).
gcf	string	Name of the GCF (ProASIC® Constraint Files) file you want to link. (Not supported for PolarFire, SmartFusion 2, IGLOO 2, and RTG4 families).
crt	string	Name of the CRT (Criticality Files) file you want to link. (Not supported for PolarFire, SmartFusion 2, IGLOO 2, and RTG4 families).

Error Codes

Example

Create a link to the file hdl1.v.
```
create_links -hdl_source hdl1.v
```
Link files to the project located at "E:\Share\abc.edn" and "E:\Share\test.v" using Environment variable "MSCC_ROOT_1" that has the root directory path "E:\Share".
```
create_links \
-convert_EDN_to_HDL 0 \
-library {work} \
-edif {${MSCC_ROOT_1}/abc.edn} \
-hdl_source {${MSCC_ROOT_1}/test.v}
```
