Convert Synopsys Technology File to Sonnet ".matl" File
This dialog box is opened when you select the command Tools - Convert Tech Process Files - Synopsys Technology File from the main window of the Cadence Virtuoso Interface. This dialog box allows you to input Synopsys (ITF) technology files and translate them into a Sonnet .matl file which can be used in the Cadence Virtuoso Interface. The controls are detailed below.
You enter the Synopsys (ITF) technology file you wish to load into the Cadence Virtuoso Interface. The ITF file should be entered in the text entry box in this section of the dialog box. There is a browse button available to the right of the entry field which will open a browse window and allow you to select the desired file or you may directly enter the pathname of the file by editing the text entry box.
This section of the dialog box allows you to enter the desired parameters for the substrate to be used with the imported process files. This defines the base dielectric layer in the stackup which is located just above the metal ground level. The entries are explained below. The PDK documentation should be consulted to determine the values used here.
Name: Enter the desired name for the dielectric material to be used in the layer here.
Thickness: Enter the desired thickness of the dielectric layer here.
Permittivity: Enter the relative dielectric constant (Erel) here.
Dielectric Loss: Enter the dielectric loss tangent here.
Conductivity (S/M): Enter the dielectric conductivity here.
Permeability: Enter the relative magnetic permeability (Mrel) here.
Magnetic Loss: Enter the magnetic loss tangent here.
This section of the dialog controls how the Synopsys file is converted to a Sonnet .matl file.
Default Via Conductivity (S/m): This sets the conductivity of all vias modeled using this .matl file. This may be changed later by editing the resulting .matl file. Enter the Conductivity in S/m in the text entry box.
This section of the dialog box defines the .matl file which is created when you translate the Synopsys file.
Sonnet .matl File: Specify the name of the .matl file to which you wish to save the translated Synopsys file. There is a browse button available above the entry field which will open a browse window and allow you to select the desired file or you may directly enter the path and filename of the file by editing within the text entry box.
