Command Reference for RFIC Dynamic Link

This appendix describes the function of each menu selection provided in Advanced Design System ( DynamicLink Menu), the Cadence Schematic window ( Tools > ADS Dynamic Link & DynamicLink Menus) and the Cadence CIW ( Tools > ADS Dynamic Link Menu item) while using the RFIC Dynamic Link.

ADS Schematic window DynamicLink Menu

_____________________________________________________________

Instance > Add Instance of Cellview...

Add a symbol of a Cadence design to the current Advanced Design System Schematic window. For example, see Adding a Symbol of the Cadence Cellview.

Instance > Update Instance of Cellview

Discards <ads_prj> /networks/ <lib> _ <cell> _ <view> .dsn and <ads_prj> /networks/ <lib> _ <cell> _ <view> .ael, regenerates an ADS symbol from the Cadence symbol, and deletes the $HOME/simulation/ <cell> directory. Deleting the $HOME/simulation/ <cell> directory forces ADS to recreate a new netlist the next time ADS requires a netlist for a Cadence subcircuit.
_____________________________________________________________

Design Variables > Get Design Variables

Add design variables from a Cadence Cellview to an Advanced Design System Schematic window. For example, see __ Adding Design Variables.

Design Variables > Update Design Variables to Cellview

Update the value of the Advanced Design System schematic design variables to the Cadence Cellview. For example, see Updating Cadence Design Variables.

_____________________________________________________________

Add Netlist File Include

Enables duplication of the Definition, Stimulus, and Model Library File include used in Cadence/Affirma. For more information, refer to Adding Model Files.

_____________________________________________________________

Top-level Design Netlist

Generate and display the Advanced Design System subnetwork netlist for the Cadence design displayed in a particular Composer window. For example, see Viewing Netlists from Advanced Design System.

_____________________________________________________________

Annotate > Annotate DC Solution to Selected Cellview

Display the DC node voltages, generated by the ADS simulator, on the Cadence Schematic Window. For example, see Performing a DC Simulation.

Annotate > Annotate Operating Points to Selected Cellview

Display the DC operating points, generated by the ADS simulator, on the Cadence Schematic Window. For example, see Annotating DC Operating Points to a Selected Cellview.

_____________________________________________________________

Set Cadence Project Directory

This is the Cadence project directory and not the ADS project directory. The subcircuit netlist for a Cadence cellview is saved as:
<Cadence_Proj_Dir> / <cellName> /adsDL/ <viewName> /netlist/netlist
The Cadence subcircuit netlist will be merged with the top-level ADS netlist under the ADS project directory and used for Dynamic Link simulation. DC back annotation data for Dynamic Link is saved in the PSF files under:
<Cadence_Proj_Dir> / <cellName> /adsDL/ <viewName> /psf
_____________________________________________________________

Close Connection

Closes ADS and terminates the link between Cadence and ADS. For example, see Ending the Session.

Cadence Schematic Window DynamicLink Menu

_____________________________________________________________

Setup Options ...

Set parameters such as Switch View List and Stop View List. The default values for this dialog are obtained from the configuration file. For more information, consult your Cadence documentation.

New Design ...

Select a new design to include in the Cadence Cellview. Set parameters such as Library Name, Cell Name and View Name. The dialog also offers a browse feature to search for existing designs. For more information, consult your Cadence documentation.

Design Variables ...

Modify the Component Description Format (CDF) information for a component so that it works with ADS. For example, see Using Design Variables. For more information, consult your Cadence documentation.

Save State ...

Save a state of a simulation. The simulation name, variables, model path, outputs and environment options are all available selections. For more information, consult your Cadence documentation.

Load State ...

Load an Analog Artist state. For more information, consult your Cadence documentation.

Subcircuit Netlist

Generate and display the Advanced Design System subnetwork netlist for the Cadence design displayed in a particular Cadence Schematic window. For example, see Viewing Netlists from the Cadence Schematic Window. For more information, consult your Cadence documentation.

_____________________________________________________________

Note If the Dynamic Link pull-down menu does not appear in the Cadence Virtuoso Schematic window, choose Tools > ADS Dynamic Link > Add Dynamic Link menu to all schematic windows in the Cadence Command Interpreter Window (CIW).

CIW Tools > ADS Dynamic Link Menu Item

_____________________________________________________________
There are two additional ADS sub-menu items accessible from the Cadence CIW.

Start ADS Dynamic Link

Launch Advanced Design System without opening a Cadence cellview.

Add Dynamic Link menu to all schematic windows

Adds the Dynamic Link menu item to the Cadence schematic window with only the Subcircuit Netlist menu item enabled. This option enables you to create a Cadence subcircuit netlist without launching Advanced Design System.
