INTRODUCTION ORCAD PSPICE 16.3 :
Cadence is the world's largest supplier of electronic design technologies
and engineering services. Cadence products and services are used to accelerate and manage the design of semiconductors, computer systems, networking equipment, telecommunications equipment, consumer electronics, and other electronics based products. With approximately 4,850 employees and 2003 revenues of approximately $1.1 billion, Cadence has sales offices, design centers, and research facilities around the world. The company is headquartered in San Jose, Calif., and trades on both the New York Stock Exchange and NASDAQ under the symbol CDN. OrCAD offers a total solution for your core design tasks: schematic- and VHDL-based design entry; FPGA and CPLD design synthesis; digital, analog, and mixed-signal simulation and printed circuit board layout. What's more, OrCAD's products are a suite of applications built around an engineer's design flow—not just a collection of independently developed point tools. PSpice and PSpice A/D are just one element in OrCAD's total solution design flow. Welcome to OrCAD. With OrCAD's products, you'll spend less time dealing with the details of tool integration, devising workarounds, and manually entering data to keep files in sync.
Our products will help you build better products, faster, and at lower cost In today’s competitive environment where time to market is critical and electronic products have shorter life spans, companies must streamline their entire product development process. Placing parts on the design directly from Digi-Key greatly reduces the chance of costly re-spins due to wrong, obsolete, or non-compliant parts, and it reduces the administrative overhead involved in validating new part requests. Having the cost information available also assists in monitoring product production costs and therefore profitability. OrCAD is the leading supplier of Windows(R) EDA software and services to electronics companies worldwide.
"OrCAD is the first company to offer this `information application ware' to its customers, and we offer it free of charge," stated Jim Plymale, OrCAD's vice president of marketing. "Engineers need easier ways to research, design-in, and procure parts for prototypes. And, electronics companies want to streamline the information flow between engineering, purchasing, manufacturing, and
ORCAD PSPICE 16.3
Vi Microsystems Pvt. Ltd., [ 2 ]
suppliers. Our Release 9.1 products enable this by making information available and actionable from within the engineer's design tools."
OrCAD's new activeparts.com design center features an online catalog of over half a million components with nearly 100,000 more being added each month. It gives engineers all available component data including schematic symbols, manufacturer datasheets, pricing, and availability from leading distributors. In Q4 1999, OrCAD expects that activeparts.com will support online purchasing of components, including prototype kitting services. The design data in the new activeparts.com online design center and OrCAD's design entry products are completely compatible. This means engineers can freely move design data across applications.
"ESI has been using OrCAD's CIS(tm) (component information system) products for some time," stated Steve Harris, electrical engineering manager, Electro Scientific Industries. "This technology enables our engineers to easily search for existing parts within our corporate-wide database. We recently had the opportunity to test-drive the new activeparts.com, and are very excited about the possibilities it has for increasing design productivity. I plan to promote the site as the starting place to go for ESI electrical engineers when searching for new part data."
The Digi-Key part database provides a number of benefits to both design engineers and companies in general. Parts can be ordered online 24/7 and received the next day. Digi-Key is a reliable source of parts that companies trust .All parametric data, RoHS compliance status, and mechanical dimensions are available Pricing and in-stock quantity information helps control costs and ensures part availability .Industry surveys consistently show Digi-Key #1 for “Breadth of Product” offered and “Availability of Product” “At Digi-Key, we take pride in finding new ways to provide the best service possible,” said Mark Larson, president and COO at Digi-Key. “Building on our success of having the number one website in our industry, we decided to make our web data available so that EMA could get our parts in front of engineers at the point of part selection. We think that this is unique in the industry and a significant step towards changing the way companies selects parts for their products.” EMA integrated the Digi-Key database into OrCAD Capture CIS by creating
ORCAD PSPICE 16.3
Vi Microsystems Pvt. Ltd., [ 3 ]
the EMA Component Information Portal (CIP). CIP is a web-based solution that can be deployed enterprise-wide, providing access to the Component Information System (CIS) behind OrCAD Capture CIS. CIP provides Engineering and Procurement with a more effective way to update the CIS database. CIP provides a user interface for users to provide new part requests and modifications for corporate approval. With the addition of the Digi-Key interface, those new part requests can now come directly from Digi-Key along with all related part information. Furthermore, EMA also offers an enterprise integration, allowing the CIS database to hold data from external systems such as ERP, MRP, PLM, and PDM. CIP becomes an easy to use, single source that combines engineering data with enterprise information. “We’re excited to have Digi-Key data available in our OrCAD schematics,” said Bruce Thivierge, manager, drafting and design services at Canberra Industries. “Having access to part cost information on the engineer’s desktop allows us to do cost roll-ups, especially for prototyping purposes. With the availability of Digi-Key part numbers and quantity on hand information, we can be confident at design time that our purchasing department will order correct parts that are immediately available. This saves time and reduces the possibility for errors.” Electronic circuit design requires accurate methods for evaluating circuit performance. Because of the enormous complexity of the modern integrated computer aided circuit analysis is essential.
SPICE is a general purpose circuit program that simulates electronic circuits. SPICE can perform various analyses of electronic circuits. SPICE contains models for common circuit elements, active as well as passive, and it is capable of simulating most electronic circuits. The acronym SPICE stands for
simulation program with integrated circuit emphasis.

� ‘Place Part’ window with libraries added and DC voltage source selected � Now if you scroll through the parts list, you’ll see a large number of elements. Since we’re building the circuit from Fig, the first part we want is a DC voltage source. We can select it either by scrolling and finding the name, or by typing Vdc in the Part menu, as shown in Fig. Once you have the part selected, click OK. Place the source on your schematic page by left-clicking on the spot that you want to place it. To stop placing sources, right click and select End Mode. Parts can be moved by simply highlighting and dragging. Now type R into the ‘Place Part’ window to start putting down resistors. Another way to do this is to type R into the pulldown menu at the top when you’re in your Schematic window. Either way, select the resistor part and place four of them on your schematic, as shown in Figure 7. To rotate a resistor, type ‘r’ (on some versions you need to type ‘ctrl+r’) while you have it selected.

Fig: Wired circuit � So, what else do we need? Remember that voltage is an energy difference between two points. PSpice calculates voltages at each circuit node, with reference to ground, so every PSpice circuit needs a ground. Each node has a number, and the software recognizes the ground as node 0. Go to the Place menu, then Ground, and type in ‘0’ since we want the ground to be named node 0. Connected it to the circuit as shown in Fig way back at the beginning, and the circuit is complete.
