Comparison with the Generic Budget AnalysisFunctions In addition to using the Budget controller in ADS analog/RF schematics, ADS also offersbuilt-in RF budget MeasEqn function capability. Here are points that compare these twobudget analysis approaches:Using the Budget controller is in addition to and does not replace the built-in RFbudget MeasEqn function capability.The Budget controller is separate from and does not rely on the built-in budgetMeasEqn function items.
The key advantages of the Budget controller over budget analysis functions are:Much easier to use.Provides many more built-in budget measurements that you can select.Provides improved budget noise measurements.Supports tuning, sweeps, optimization, yield, etc.Supports AGC loops.Supports selection between alternate budget paths.Supports export of results in ASCII files for use in third-party tools, including Excel. The advantages of built-in RF budget MeasEqn function capability are:Supports flexible circuit topologies.Supports more flexible path selection.Supports user-defined subnetworks with frequency conversion.Supports more general mixer models.Supports concurrent simulation with other analog/RF analyses.

Aspen Cim-IO for OPC User's Guide
http://www.cadfamily.com/downinfo/300909.html
OLE for Process Control (OPC™) provides a common method for applicationsto access data from any data source (such as a device or a database) withouthaving to know about the specificity of the device or the database.Applications communicate with OPC servers in a standard way, independentfrom the data source.
The Cim-IO for OPC Interface is used to transfer data between OPC serversand Cim-IO Client programs, such as InfoPlus.21™, DMCplus™, user-writtenCim-IO Client programs, etc.The Cim-IO for OPC Interface consists of a Manager program, which startsand stops the Cim-IO for OPC Servers.
Cim-IO for OPC Servers are processesthat communicate with OPC Servers. One Cim-IO for OPC Server exists foreach OPC Server installed on the system.Cim-IO for OPC Servers receive Cim-IO requests from Cim-IO clients (GET,PUT, UNSOLICITED GET) and send replies to these clients.

Agilent-Dynamic Access for Mentor
http://www.cadfamily.com/downinfo/300902.html
License Requirements
To use Dynamic Access for Mentor, ensure that you have valid licenses for the ADSschematic and layout environments. No additional ADS licenses are needed. For moreinformation on ADS licenses, see Setting Up Licenses for Windows Installation (instalpc).For Mentor licenses, check with your local corporate Mentor administrator.
Dynamic Access for Mentor Library RequirementsAn RF design started in ADS can be transferred to Mentor for inclusion in a larger PCBsystem. To transfer parameterized information about the components and interconnects that make up the design, ADS and Mentor must share compatible libraries, with identicalsymbols and layout footprints. For simulation, the ADS library must include electricalmodel information for each element in the schematic.
In the past, this has requiredextensive custom library development work.With the schematic and layout RF Options, Mentor now provides compatible symbollibraries for most passive ADS elements, including transmission line components such asmicrostrip and stripline. This means that ADS designs that use these elements can moveinto the Mentor environment without user-supplied libraries.The Mentor side of the Dynamic Access for Mentor link includes utilities to create andmanage the ADS-compatible symbol library.

Using SMT Package Artwork as Artwork ReplacementThe procedure for using the SMT package artwork as an artwork replacement is similar tousing the standard artwork replacements. In the Design Parameters dialog box, changethe artwork type to AEL macro and define the two parameters, SMTPAD and OFFSET. Setthe SMTPAD parameter type to string.
SMT Artwork Replacement Examples shows an example for using the SMT package layoutartwork library AEL function as an artwork replacement, through the ParametricSubnetwork (PSN). Underlying the network 3PortSubNet is the element S3P, that can beviewed by pushing into the component. \
In the Design Parameters dialog for thesubnetwork, 3PortSubNet , the Artwork Type is set to AEL macro and Name is set tosmtart_SOT23. Two parameters, SMTPAD and OFFSET, are defined in the DesignParameters dialog. Set the SMTPAD parameter value to String, with "Pad1" as its defaultvalue. Set the OFFSET parameter type to real , with 0 as its default value.
