APT Software - Clients

Sense Intellifield is an innovative supplier of integrated automation and information systems for drilling and well contractors and manufactures a wide range of products, ranging from single control systems for machinery to integrated screen based automation systems.

We are working closely with Sense Technology to develop a Server and associated Components conforming to the WITSML specifications as part of their SiteCom suite of offerings for Remote Operations. We have developed the system in the .NET platform with C# as the development language. We collaborated on all aspects of software development including design and testing.

Ecrio inc, Cupertino, CA, USA

Ecrio(tm) is a provider of advanced wireless messaging software to wireless carriers, portals, service providers, and corporations. The Ecrio Rich Instant Messaging Platform, the Ecrio Intelligent Delivery Engine, and the Ecrio Communication Gateway handle All Media(tm) content and support devices such as PDAs, WAP and SMS enabled phones, and desktop computers.

We work closely with Ecrio on software development for their Instant Messaging Platform, both for the Server and for the Clients, including Palm, PocketPC, J2ME devices and Symbian phones. We also perform software testing and QA for their products. We developed a J2ME Client conforming to the Wireless Village specifications. We are also working on developing an engine for Push to Talk over Cellular which conforms to the OMA (Open Mobile Alliance) specifications.

Network Computer House, Bologna, Italy

NCH specializes in banking software and provides software tools and services to about 80% of the banks in Italy. We have successfully developed and Level 2 certified an EMV Kernel for ATM Machines. The development was in Microsoft .NET enviroment. We have also developed a cross platform high-level communication protocol,to allow banking applications to communicate across multiple platforms including Win95, WinNT, Solaris and AIX. The implementation was in C++. We implemented the layers corresponding to the Layers 5, 6 and 7 of the OSI model. We also implemented a Zmodem like protocol for Layer 4.Currently we are also developing Retail and Banking solutions for them using J2EE technologies like Spring, Hibernate, JSP, Struts, Websphere AS and Websphere MQ.

We have developed a detailed Procedure and Guideline for Test Plan preparation, which is in the process of introduction at NCH. We also undertook a study on selection of a test tool for NCH; and Rational Corporation’s products have been recommended.

Geologix Limited, UK

Geologix is developer of the GEO Software Suite of PC-based, well log data management applications. We are currently developing software for some of their products namely, GeoX-Section and GeoGraph.

Terablaze Inc., USA

Terablaze (subsequently acquired by Agere) was a provider of switch fabric subsystems including chipsets, reference designs, software and full-blown demo systems. The switch fabric was scalable upto multi-terabits and a single device can support several hundred Gbps. The port speeds were 10Gbps and above.We worked closely with Terablaze in defining and developing a verification platform at the System and Block level.

Applied Simulation Technology Inc., San Jose, CA, USA

We developed a software tool in Java (Sun JDK 1.1.7) for easy creation, edits and view of model files conforming to the IBIS (Input/output buffer interface specification) standard ANSI/EIA-565. We also developed a circuit simulator for simulating very large linear circuits, specially those derived from parasitic extraction.

EIA IBIS Open Forum, USA

The IBIS Forum is an organization of semiconductor vendors, EDA (Electronic Design Automation) software vendors and IC end users, who have developed the ANSI/EIA 656 standard for exchange of model information,for input/output buffers used in ICs.A parser for checking compliance of IBIS buffer model files against the ANSI/EIA-656 standard was implemented by us in C.

Enable Semiconductor Inc., Milpitas, CA, USA

Enable (subsequently purchased by Lucent) was a fabless design house,specializing in Ethernet 10/100 transceiver chips. We consulted for them,on the EDA aspects of their designs.

We developed analog behavioral models for their PLL circuitry in the spectreAHDL modelling language.
We characterized their standard cells for timing delays.
We developed software in C to analyze delay paths for their circuits.
We optimized their filter circuits using the Hspice circuit simulator.

Technology CAD Division, National Semiconductor Corporation, USA

We have worked closely with the Technology CAD and LAN Divisions of National Semiconductor. We implemented new GUI features and proprietary models in their device model parameter extraction tool and in their in-house circuit simulator. We also worked on developing their cell library for the Cadence framework and on integrating their circuit simulator within it.

We developed high level analog behavioral models for analog blocks in National's transceiver chip DP83223A using spectreHDL under Cadence OPUS 4.3.2.

We generated IBIS models for the entire range of their Clock Generation and Support chips. We developed a tool for accurate generation of timing parameters from standard cell layouts. The tool was interfaced with other CAD tools in National,to allow the user to extract circuit simulation netlists from the layout, perform characterization runs, generate a database of timing parameters and output annotated netlists for timing analysis. A novel technique for setup/hold time computations was also implemented.
