[casper] Matlab 2012b simulation problem
Hi All, I'm trying to run a simple simulation on an ADC block. I'm just changing the frequency of the input sine wave. Unless I refresh the ADC block (change frequency etc) then the simulation fails to run correctly - no sync pulse generated and the output of the ADC is always zero (a scope on the sine simulator does show the correct wave). I also get the following warning: Warning: did not properly cleanup after previous model termination2012 Any ideas much appreciated as it's a real pain at the moment to run anything.

[casper] Matlab components for toolflow
Hi fellow CASPERians, This is a question that comes up periodically. At SAO we are now paying full fare for Matlab licenses so the cost impact of an imperfect understanding can be significant. The latest MSSGE wiki page is: https://casper.berkeley.edu/wiki/MSSGE_Setup_with_Xilinx_14.5_and_Matlab_2012b However this page does not mention Matlab optional components (historically termed toolboxes and blocksets). There are clues in an earlier setup page: https://casper.berkeley.edu/wiki/MSSGE_Toolflow_Setup from which it appears one needs something like: Fixed-Point Toolbox Signal Processing Blockset Signal Processing Toolbox Simulink Fixed Point Each time I buy a new license I iterate on these components with the Matlab distributer. The terminology changes year by year and I am currently being quoted on the following components, in addition to the base Matlab and Simulink distributions: SIGNAL PROCESSING TOOLBOX, V2013A SIMULINK FIXED POINT, V2012B DSP SYSTEM TOOLBOX, V2013A FIXED-POINT DESIGNER TOOLBOX, V2013A, (sorry about the all-caps which pasted in directly from the quotation). So it is still four components, but the names have changed. The term blockset seems to have evolved out in favor of toolbox, one of the signal processings has morphed into DSP, and the fixed point toolbox now has designer. Appropriately enough the price for this latter designer component alone has more than doubled in a year to over $2k per seat. Having set the scene, my two questions are: 1. Are we ordering the right components? 2. Do we really need all these components? (At one point I seem to recall hearing the fixed point stuff is to some extent optional, though the ability to simulate properly at the Simulink level is important to us.) Subject to confirmation from the tool flow experts, I will be happy to update the wiki notes with current information. Thanks, Jonathan
Re: [casper] Matlab components for toolflow
As one data point I'm successfully compiling designs w/o the fixed point toolboxes. I haven't tried simulating a large design which is where it's claimed to be needed with busses wider than 53 bits or whatever it is On Sep 17, 2013 7:15 PM, Jonathan Weintroub jweintr...@cfa.harvard.edu wrote: Hi fellow CASPERians, This is a question that comes up periodically.
