6. P hilosophy All design approaches to problem solving with computation devices are essentially problems of logic irrespective of a hardware or software solution. All design solutions have a unique philosophy and structure within a logic framework. Designs cannot be effective until the philosophy of the solution is understood. All logic problems have a ‘natural’ solution. All logic solutions should be designed without prejudice towards a hardware or software solution initially.

7. Technical Focus Low-level hardware/software logic design with emphasis on: digital logic logic interfaces to code hardware programming for device drivers diagnostics for project bring-up and long term testing System level logic work with emphasis on: Embedded work for device drivers & diagnostics Device drivers for SCSI & storage devices for both embedded and operating systems Software emulation design of SCSI peripherals for testing

8. Logic Design Approach Top-down design Customer oriented solutions Strong emphasis on documentation: MRDs (marketing requirements documents) Past product input Layered design approach in least to most specific: Initial specifications, customer requirements, past product input High level block diagrams State/logic diagrams Data/control flow specifications
