If any of you folks would like to help correct or add to the science, or just be a reader, I would love to add you to the list for whatever amount of reading you would like to do. This will start near the end of summer. Below is a description of the project, if anyone has the time. Thanks so much in advance:
Books Objective The purpose of this book is to get everyone from early readers to armchair adults to read, enjoy, learn and perhaps postulate about the improbable, and the possible. The potential, and the value of cooperation and teamwork. The power of many minds can have on one extremely difficult problem, and the improbability making that happen amongst nations. And, finally, to learn the difference between science and science fiction. The American public is woefully under-educated in any of the sciences, especially the hard ones. So, I hope to engage these folks with not just a good story, but a plausible one about why there is life on earth, and why life elsewhere, even if it's mostly microbial is “almost” certain. I provide the current thinking about the likelihood of sentient life elsewhere. Another main element is how that “contact” might take place. I don’t think will be a duke out with the US. Marine Corps in Los Angeles. I suggest it might be a somewhat more subtle approach. In the end, I hope to interest people in learning just a little more. Since certain scientific concepts and jargon are unavoidable, I hope to skirt this issue by embedding QR readers and Hyperlinks taking the questioning reader to sites like Scientific American, NASA and even the books appendix and glossary for explanations. My biggest challenge is to write to a level that a high school reader will be interested in. YOUR HELP: That's where my readers come in. Typos, readability, plot development, interesting story, and most importantly understandable without scientific errors. STORYLINE: Darkfield Explorer The fundamental elements of the story are two young girls who move in next door to a retiring physicist and teacher who takes an interest in their scientific curiosity. He is a bit of a polymath himself and engages their natural childhood curiosity. Both go on to get Ph.D.’s, and in the course of their dissertations find a very a very unexpected and perhaps serendipitous connection. One of the girls develops an instrument capable of seeing the interactions in the energy contained in "empty" space. Perhaps a Millisecond neutron burst? In the course of this, she detects something in the asteroid field just past Mars. Just far enough to prevent our current imaging or detection, which is size relative. Her best friend and neighbor does her dissertation in geophysics and discovers something stunning and equally unexpected within the ELF radio waves generated during seismic activity. ----- Original Message ----- From: "Heystek Grobler" <heystekgrob...@gmail.com> To: "Adam Isaacson" <aisaac...@ska.ac.za> Cc: "Casper Lists" <casper@lists.berkeley.edu> Sent: Monday, August 15, 2016 10:46:26 AM Subject: Re: [casper] Help with Xilinx and Simulink Hi Adam and James I am working on my personal computer. I will ask a IT guy to help me with the privileges and also clone the mlib-devel into the home directory and try to run it again. Thanks for all your help.

I suggest you follow what James suggests. The fact that you can't run sudo though means that you may need your IT guy to give you sudo rights, but if you are working off the university server that may be an issue - as James says, you shouldn't need this if you install into your home directory.

I have attached my matlab startup scripts (startsg and startup.m). These must be placed in the "mlib_devel" directory. You will probably have to change the paths to where your installs are. All you need to do is the following: 1) Startup matlab R2012b, by running the startsg script. Using the Ubuntu terminal, in the "mlib_devel" directory type: "./startsg". This should startup matlab. There should be a message saying that "system generator currently found installed in matlab default path..." 2) Type in "simulink" in the command window. 3) The Simulink Library Browser will open. Browse to where your model is located and select the *.slx file. 4) The model should open. Press "Ctrl + D" to check for any errors. There should be no errors. 5) Type in "casper_xps" in the command window. The casper XPS window should pop up. Make sure all boxes are ticked under "ISE Design Flow Choice:" and then click on "Run XPS". This will run the system generator as part of the process, the Xilinx ISE and generate the relevant bit, fpg files. I have also attached scripts if you just want to run the programs individually - you will need to edit the path to where your installs are. Good luck. This should get you going. If the scripts bomb out then it is likely that your paths are not correct - check that first.

This contains a Virtex 6 device. Vivado only works with Virtex 7 onwards. I would suggest if you are going to target the ROACH 2 that you use Xilinx ISE 14.7. You will need to work with ISE 14.7 and not Vivado. We have just begun to use Vivado for our Virtex 7 board e.g SKARAB. As far as I am aware, all the the ROACH2 development in SKA-SA has been done using Xilinx ISE 14., as it supports Virtex 6 devices.

I am an electrical en electronic engineering science student and for my final year project (skripsie) I'm developing a wideband spectrometer on a ROACH-2 board. Currently I have a problem with Xilinx System Generator and MATLAB. The Simulink Model runs as a simulation but as soon as I run it in Xilinx System Generator to compile it for the board it crashes and gives a "design error" as and "block error". I was hoping that if possible, that you could provide me with assistance to get Xilinx and Simulink up and running. So far I followed the CASPER tutorials but got stuck with this problem/ I hope to hear from you soon.
