Experiences in Using Open Source Software for Teaching Electronic Engineering CAD
Experiences in Using Open Source Software for Teaching Electronic Engineering CAD Dr Simon Busbridge1 & Dr Deshinder Singh Gill School of Computing, Engineering and Mathematics, University of Brighton, Brighton BN2 4GJ [email protected] Abstract Embedded systems and simulation distinguish modern professional electronic engineering from that learnt at school. First year undergraduates typically have little appreciation of engineering software capabilities and file handling beyond elementary word processing. This year we expedited blended teaching through the experiential based learning process via open source engineering software. Students engaged with the entire electronic engineering product creation process from inception, performance simulation, printed circuit board design, manufacture and assembly, to cabinet design and complete finished product. Currently students learn software skills using a mixture of electronic and mechanical engineering software packages. Although these have professional capability they are not available off-campus and are sometimes surprisingly poor in simulating real world devices. In this paper we report use of LTspice, FreePCB and OpenSCAD for the learning and teaching of analogue electronics simulation and manufacture. Comparison of the software options, the type of tasks undertaken, examples of student assignments and outputs, and learning achieved are presented. Examples of assignment based learning, integration between the open source packages and difficulties encountered are discussed. Evaluation of student attitudes and responses to this method of learning and teaching are also discussed, and the educational advantages of using this approach compared to the use of commercial packages is highlighted. Introduction Most educational establishments use software for simulating or designing engineering. Most commercial packages come with an academic licence which restricts access to on-site computers. -
Bridging the Gap Between Precise RT-Level Power/Timing Estimation and Fast High-Level Simulation
Fakultät II – Informatik, Wirtschafts- und Rechtswissenschaften Department für Informatik Bridging the Gap between Precise RT-Level Power/Timing Estimation and Fast High-Level Simulation A method for automatically identifying and characterising combinational macros in synchronous sequential systems at register-transfer level and subsequent executable high-level model generation with respect to non-functional properties Dissertation zur Erlangung des Grades eines Doktors der Ingenieurwissenschaften von Dipl.-Inform. Kai Hylla Gutachter: Prof. Dr. Wolfgang Nebel Prof. Dr. Wolfgang Rosenstiel Tag der Disputation: 13. Januar 2014 Abstract Knowing a system’s power dissipation and timing behaviour is mandatory for today’s system development and key to an effective design space exploration. Not only does battery lifetime or design of the power supply directly depend on the power dissipation of the system. Second-order effects such as thermal behaviour or degradation effects that are directly or indirectly affected by the power dissipation must be considered, too. Various techniques for power estimation exist at different levels of abstraction. Low-level approaches provide accurate estimation results but require a lot of computational effort. High- level approaches however, allow fast and early estimates, but lack of a deeper knowledge and understanding of the hardware, implementing the behaviour. Therefore, they can only give rough estimates. What is missing is an approach allowing fast and early estimates with respect to as many relevant hardware artefacts and physical properties as possible. This doctoral thesis tackles the problem of a fast, yet accurate power and timing estimation of embedded hardware modules at a high-level of abstraction. A comparatively time consuming low-level estimation is performed once in order to obtain an accurate estimate. -

While certain steps require linear progression, iteration and revision of earlier stages also happen. Overall, EDA tools only support a small part of this process, and moving between steps was a major source of friction.

Digital Sensors Operate on 3.3V
Worcester Polytechnic Institute A Major Qualifying Project AURORA Autonomous Unpowered Recovery of Radiosonde Aircraft Submitted By: Richard Eberheim, Robotics Engineering Nicholas Hassan, Robotics Engineering and Electrical & Computer Engineering Joshua O’Connor, Mechanical Engineering Advised By: Kenneth Stafford, Professor Robotics Engineering, Mechanical Engineering Fred Looft, Professor Electrical Engineering This report represents the work of WPI undergraduate students submitted to the faculty as evidence of completion of a degree requirement. WPI routinely publishes these reports on its website without editorial or peer review. For more information about the projects program at WPI, please see http://www.wpi.edu/academics/ugradstudies/project-learning.html Abstract This project developed an autonomous radiosonde glider that actively steers itself from the apex of its flight to safe recovery locations on the ground. This enables easy and reliable recovery, reducing costs and offering new capabilities to atmospheric researchers. The glider integrates the essential weather sensors used on current radiosondes with those needed for autonomous flight in a durable, easy to manufacture airframe capable of multiple data gathering flights with minimal repairs between each flight. 1 Acknowledgments This project was made possible through the support, guidance, and assistance of the staff and students of Worcester Polytechnic Institute. We would like to thank Professors Ken Stafford and Fred Looft for advising the project. We would also like -
Performed the Most Often. in FPGA Design Flow, Functional and Gate
performed the most often. In FPGA design flow, functional and gate-level timing simulation is typically performed when designers suspect that there might be a mismatch between RTL and functional or gate-level timing simulation results, which can lead to an incorrect design. The mismatch can be caused for several reasons discussed in more detail in Tip #59. Note that the nomenclature of simulation types is not consistent. The same name, for instance “gate-level simulation”, can have slightly different meaning in simulation flows of different FPGA vendors. The situation is even more confusing in ASIC simulation flows, which have many more different simulation types, such as transistor-level, and dynamic simulation. The following figure shows simulation types designers can perform during Xilinx FPGA synthesis and physical implementation process. Figure 1: Simulation types Xilinx FPGA designers can perform simulation after each level of design transformation from the original RTL to the bitstream. The following example is a 12-bit OR gate implemented in Verilog. module sim_types(input [11:0] user_in, output user_out); assign user_out = |user_in; endmodule XST post-synthesis simulation model is implemented using LUT6 and LUT2 primitives, which are parts of Xilinx UNISIMS RTL simulation library. wire out, out1_14; LUT6 #( .INIT ( 64'hFFFFFFFFFFFFFFFE )) out1 ( .I0(user_in[3]), .I1(user_in[2]), .I2(user_in[5]), .I3(user_in[4]), .I4(user_in[7]), .I5(user_in[6]), .O(out)); LUT6 #( .INIT ( 64'hFFFFFFFFFFFFFFFE )) out2 ( .I0(user_in[9]), .I1(user_in[8]), .I2(user_in[11]), .I3(user_in[10]), .I4(user_in[1]), .I5(user_in[0]), .O(out1_14)); LUT2 #( .INIT ( 4'hE )) out3 ( .I0(out), .I1(out1_14), .O(user_out) ); Post-synthesis simulation model can be generated using the following command: $ netgen -w -ofmt verilog -sim sim.ngc post_synthesis.v Post-translate simulation model is implemented using X_LUT6 and X_LUT2 primitives, which are parts of Xilinx SIMPRIMS simulation library. -
