This paper will discuss the process and efforts that Raytheon Electronic Systems has experienced to specify, install, maintain and use the Mentor LMS product with the PDS option. Over the past eighteen months RES has been working toward using LMS and PDS to enhance our process and improve the designs fed into the Boardstation tools. We started by contracting with Mentor to work with us to identify our existing process and the process we wanted to move toward, specify the custom RES environment, create a comprehensive LMS Specification, and implement the structure as specified. RES then initiated a transition effort to begin to use the process that uses the library. We are well into the transition, with new designs using parts developed in LMS. We are using DA_LMS with TO_LAYOUT, ENGINEERING VIEW with High Speed Design Rules, and BOARDSTATION. The paper will describe some problems and solutions of maintaining and synchronizing LMS configurations and libraries at four separate sites. We are still learning.

Bio:
James Garretson has worked with Mentor tools since version 5.2 (1986), when our MGC technicians used hand trucks to move the DSP-90?s 500MB hard disks. While learning the hardware design process as an electrical designer, he started in CAE with FutureNet and moved on by becoming a Mentor System Administrator with Apollo?s Domain OS. While Mentor has switched to UNIX, Jim?s concentration has shifted from sys admin to supporting proprietary tools that augmented Mentor tools, and on to coordinating library development for several electrical hardware design laboratories. He is also currently a member of a team working to standardize the EDA libraries in the new Raytheon Systems Company.
