I would be great to get boards that could be integrated into a target hardware as it is done i.e. with the LPCXpresso boards from NXP, where the part of the board that is next to the USB and JTAG I/F is so small that it can be integrated into a target hardware, allowing for a simpler PCB. In case of the FPGAs this would mean to define boards, probably targeting a group of applications that would benefit from using it
@Steve470: I had something like that too; it defaulted the path name to someplace on the C: drive, but my project was actually on the E: drive. Using the browse button, I found the file, and the path doesn't even show up in the field anymore. Good Luck.
@opamp: Okay found what you were talking about. It had the correct file name and directory location, but when i tried to regenrate, it told me the file doesn't exist. Went back in, opened the browser, and yet there it was, exactly as it appeared in the file name dialog box. I'm stumpped! perhaps the directory structure is too deep. Other IDEs I'v worked with occasionally have that issue. I'm going to try moving the project.
@Steve470: I don't know. When I double-click the filename in the File List, the IPexpress tabs open and I get a popup window to set the configuration for the module. I think the first time, I got an error that said it was the wrong version, and I selected Regenerate. But the regeneration didn't work (the first time) because the wrong Memory File was selected in the configuration.
@opamp: I have been using "CDM 2.04.06 WHQL" and it is in not working. I noticed that the fedibus.sys is in the "CDM 2.04.06 WHQL\i386" directory. I may have the righr driver and have check and rechecked the settings and unistalled and reinstallled several times.
fiy ann- sound start for 'radio' announcement, quit running, but then, just before i could click run, 'started' again in middle of your announcement. Then, about 5 minutes later, sound blanked out [not stopped] for about 10 seconds and restarted. a blank out happen yesterday as well.
@karstdiver- Check out one of the tutorial docs or a video shat shows simulation. You create a set of test vectors that are applied to your design and then you can see the output. Look for a simple design example (like a counter) as a first step.
@Steve470: In the Initialization section, there is an entry for Memory file. Be sure to select "lcdcarmap.mem" - when I initially browsed for the file here, there were two options, only this one works.
? In the Power Control demo, one IPexpress file, LCDCharMap.ipx, will not regenerate - message says "Module ROM Version:5.0 is not supported". Simplify refuses to do anything with the project, and just says it is out of date. Anyone know how to get past this?
? Warren, when synthesizing the demo project I got : Error: VCP2741 source/demo_top_config.v : (315, 1): Named port connection is not allowed for UDP instance: \\1 \. UDP instance assumed from the use of strength or an unnamed instance.
It gave an error "Error: VCP2741 source/demo_top_config.v : (315, 1): Named port connection is not allowed for UDP instance: \\1 \. UDP instance assumed from the use of strength or an unnamed instance."
@Ken and other having trouble with USB: After installing the drivers, plug in the board and wait for the tones to indicate that Windows has recognized the board. Then use your terminal program to set the COM port and the baud (115200).
Hi all -Audio is live! If you don't see the audio bar at the top of the screen, please refresh your browser. It may take a couple tries. When you see the audio bar, hit the play button. If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version. Some companies block live audio streams, so if that is the case for your company, the class will be archived on this page immediately following the class and you can listen then. People don't experience any issues with the audio for the archived version.
One thing I noticed in connecting to the PICO board, is that the USB com port likes to set itself up as COM16. I have to go into the hardware manager and manually change it to COM2(my choice), and things start to talk.
When I opened the low power demo, I got a message about converting from 1.3 to 3.0. It still opened, but showed 14 warnings, all appear to be about bit length 7 differs from formal bit length 8. I'm assuming this is related to defining characters for the 7 segment display.
Other than that, Diamond appears to be intact, and accepting the license file.
Has anyone been able to run the demos? I haven't been able to successfully run any of the demos without errors. Some of the process steps run without error (but lots of warnings), but I've never been able to get through all the steps. The demos seem to have been created in an older version of Diamond; maybe the conversion doesn't set all the strategy entries correctly. I WAS able to regenerate the IPX files for the new version - at least it appears to have worked. Any ideas?
You are eligible to earn IEEE Professional Development Hours by attending these courses and participating in the chat function. Additionally, we are no longer using the points system, offering "graduation", or giving grades. The IEEE hours are taking the place of that. There are some important things for you to know about earning the hours. The most important ones are that you need to attend these courses live, you need to attend a minimum of two of them per semester, you need to fill out a course evaluation form within 2 weeks of the end of the class, you need to attend 4 out of the 5 classes per course, and you need to participate in the chat function every day you attend. Please click on the link at the top of this page that says "How do I earn IEEE professional development hours" to read all of these important details and more.
When I load the sample power control project I get 14 warnings. Eight of them are "redeclaration of ansi port LCDxxxx is not allowed." One is "instantiating unknown module count16_ldrg". Four more are associated with the LCD: "actual bit length 7 differs from formal bit length 8 for port LCDx." And the final one is "actual bit length 32 differs from formal bit length 1 for port OutClockEn."
I'm guessing that the ones about bit length are unimportant, the others may be important. I don't have a board so I can't test.
Has anyone else seen similar results? Does the demo actually work?
I have been unable to sucessfullly connect to the board. I have tried different computers, terminals. I type "m" in the terminal and nothing happens. Reset doesn't work either. I get the power lite but nothing else.
Go to http://www.latticesemi.com/Products/DesignSoftwareAndIP/FPGAandLDS/LatticeDiamond.aspx Click on Support at the bottom of the page. Click on Request License. You will need to provide your 12-digit MAC address. You can get this by going into a Command Prompt and entering ipconfig /all. You'll see the address next to Physical Address. Check your email for the license.dat file and put that in the \license directory where the Lattice Diamond is installed. Voila!

The streaming audio player will appear at the top of this web page when the show starts at 2 PM Eastern time today. When you see it, click on the play button to start the audio. Note however, that some companies block live audio streams. If when the show starts, the audio bar doesn't appear or you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser. Some users experience audio interruptions with IE. Also, make sure your flash player is updated with the current version. If that doesn't work, the class will be archived immediately following our live taping. You shouldn't experience any problems with the audio when listening on-demand.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
