Abstract
Abstract Disclosed is a schematic capture and design verification system wherein the graphic symbol (402) linked to a component is separated from the model (422, 426) used to simulate the component. Each component has a graphics symbol (402) linked to a link or scion page (404). The link page (404) also contains a list of all models that can be used with the component. The system allows a model to be selected (406) for each component in a schematic, and allows the model to be changed at any time. The system also allows the models for all components to be changed with a single command. The user enters a schematic (602) into the system, then selects a model for each component used in the schematic. After a model has been selected for each component, the user requests the system to build a netlist that describes the schematic to a simulator or other analysis or synthesis tool. In building the netlist (616), parameters are extracted from the link page for each component and included in the netlist to be used by the simulator. When a different simulation is desired by the user, the user instructs the system to change the model linked to the components to a new model suitable to the second simulator. The system then builds a new netlist, using parameters specific to the new model and the second simulator.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
86 words
In a design capture system, a process for using a single symbol (402) for a plurality of models (422, 426) comprising the steps of: creating a link page (404) for said symbol (402); linking said symbol to said link page; creating a plurality of model couplers (410, 412) on said link page, one for each of said plurality of models; linking one of said couplers to each of said plurality of models (411, 413); and linking said symbol to a predetermined one of said couplers (406).
Claim 2
Dependent Claim
175 words
In a design capture system having a plurality of symbols (402), a process for capturing a schematic (602) from a user of said system and for using one of a plurality of models (422, 426) for each of said symbols comprising the steps of: (a) creating a link page (404) for each of said symbols; (b) creating a plurality of model couplers (410, 412) within said link page, one for each of said plurality of models (422, 426); (c) linking one of said couplers to each of said models (411, 413); (d) linking one of said symbols (402) to each of said link pages (404); (e) capturing a schematic (602) comprising the steps of (e1) accepting from the user a list of selected symbols (604, 606, 608), and (e2) accepting from the user a list of connections between said selected symbols; (f) accepting from the user a model type for each of said symbols; and (g) linking each of said selected symbols to one of said plurality of couplers identified by said model type (406).
Claim 3
Dependent Claim
31 words
The process of claim 2 further comprising the step of: (h) accepting from the user values for one or more parameters (414, 416) within each of said model couplers (410, 412).
Claim 4
Dependent Claim
25 words
The process of claim 3 further comprising the step of: (i) combining said list of connections with said parameter values to produce a netlist (616).
Claim 5
Dependent Claim
78 words
A design capture system having a symbol (402) and a plurality of models (422, 426) comprising: a link page (404); a plurality of model couplers (410, 412), one for each of said plurality of models (422, 426), within said link page (404); means for linking said couplers to said models (411, 413); means for linking said symbol to said link page; and means for linking (406) said symbol (402) to a predetermined one of said couplers (410, 412).
Claim 6
Dependent Claim
155 words
A design capture system having a plurality of symbols (402) and a plurality of models (422, 426) for allowing a user to input and process a design, said system comprising: a link page (404) for each of said symbols; means for linking one of said symbols to each of said link pages; a plurality of couplers (410, 412) within each of said link pages (404), one of said couplers for each of said models (422, 426); means for linking each of said couplers to one of said models (411, 413); means for capturing a schematic from the user comprising means for accepting a list of selected symbols, and means for accepting a list of connections between said selected symbols; means for accepting from the user a model type for each of said symbols; and means for linking each of said selected symbols to one of said plurality of couplers identified by said model type (406).
