We suggest you adopt the following procedure to get started - Firstly, obtain your free Hevday Interactive Logic software and install it. You can obtain the software via our Download page. The install uses the standard Microsoft installer procedure. Once installed you will be able to try out the various facilities provided, such as the multi-level schematic editor, and the state diagram and symbol editors, and you can review it to establish if it suits your needs. You can also look at the data and signal display windows, but will not be able to view actual signals or data or run your circuit until you have a Logic Module operational and you will need Xilinx development software prior to compiling your circuits. Next obtain and install a copy of the free Xilinx ISE WebPACK, version 6 or 7, from the Xilinx Download Center accessible via the Xilinx website, and license it as required. The Xilinx software is required before you can compile a circuit to download into a Hevday Interactive Logic Module. You can try designing and compiling circuits at this stage. Finally, purchase a Hevday Logic Development Kit. This will provide you with a Logic Module, a Communications Card and a power cable. You will need to provide a power supply and a standard network cable. The power supply should be rated at 5VDC ± 5% with at least 0.5A continuous output. The supply voltage should always stay within the 5VDC ± 5%, and supply noise, ripple and transients should not take it out of that region at any time. Operating the Logic Module at a high clock rate with heavy I/O usage may require more current than 0.5A. The network cable should be a straight through cable if it is to connect to a network hub, or a crossover cable if the Communications Card is to be connected directly to a PC network port without any other devices on the network. You may need a crossover cable during set-up. The Communications Card will work with either a 10MHz or 100 MHz network.
First time starting with a new Logic Module Follow these steps - 1. Plug the Comms Card into the two 34 way sockets on the Logic Module. Make sure the connectors mate correctly with all pins fully in the sockets.

2. Attach the power cable to the Logic Module Power Connector with the power supply turned off. The yellow wire is taken to the power supply +5VDC±5% terminal and the black wire taken to 0 Volts. 3. Make sure the No Load from ROM Jumper is removed. 4. Turn the power supply on. The yellow Power-on LED beside the heatsink nearest the power cable should light. The green Run LED at the opposite corner of the board should also light indicating the default circuit stored in the on-board flash ROM has been loaded and is running. If you wish, you can use an oscilloscope to view the waveforms on the user I/O pins. JP_3_10 has a signal changing about once per second 5. Connect directly from the network port on your PC to the Comms Card Network Connector using a standard network crossover cable rated for a 100MHz data rate. 6. If you now follow the Help System Network Hardware Set-up instructions to set up your network addresses, you should be ready to connect to your Logic Module. 7. When you are ready, click the connect button that lets you monitor the project currently in the hardware.
The software will then start communicating with the hardware, and will determine which project is resident, load the appropriate schematics, and start displaying the data and signals showing how they are changing. You can then pause, single step and run the circuit, display circuit data in the Data Display, or otherwise familiarize yourself with the operation of the system. With the schematics visible, you can see which I/O connector pins to probe with your oscilloscope. As a next step, we suggest you have a look at our Getting Started and Tutorial documents. |
