58. SimPhonics, Inc. Configuration is Saved in.VNE File CONFIG.VNE File

59. SimPhonics, Inc. V+ Development System 1.User enters/edits a design 2.User presses the play button 3.V+ Editor checks for visual errors 4.Error messages printed to Editor Message Window

60. SimPhonics, Inc. Open Pin Error

61. SimPhonics, Inc. V+ Development System Once all errors are cleared: V+ submits design to the Run- time system. When the design is submitted, the following message appears: “Trying to Start Platform…”

62. SimPhonics, Inc. Design Time Object List (DTOL) The DTOL is the list of ports, objects, static data, and connection information. The Run-time system then begins the process of trying to run the DTOL

63. SimPhonics, Inc. DTOL Submission DTOL

64. SimPhonics, Inc. Run Time System 1.Accepts DTOL from Editor 2.Verifies objects are in inventory 3.Verifies ports are in inventory 4.Tries to start objects and devices

65. SimPhonics, Inc. Run Time System Message Window Scrollable message area

66. SimPhonics, Inc. Run Time System Pre-Execute Phase Each device and Object may halt pre-execution. Most will display an error in the message window. Once all objects and devices report they can start: The DTOL is executed.

67. SimPhonics, Inc. Run Time System Post-Execute Phase Each device and Object is asked to stop during user stop commands. Once all objects and devices report they can stop: The DTOL execution is halted. Again, read your message window.

68. SimPhonics, Inc..VNE File DTOL and Configuration Configuration is always saved with.VNE file. DTOL is only saved if a successful execution has occurred.

69. SimPhonics, Inc. Configuration is Saved in.VNE File CONFIG.VNE File DTOL

70. SimPhonics, Inc..VNE File – Updating Anytime the design or configuration has changed, the.VNE file must be resaved. The.VNE file is similar to a.EXE file in this sense.

71. SimPhonics, Inc..VNE Files – Auto-booting The.VNE file may be executed directly. Insert the.VNE file into the STARTUP folder for auto-loading the system at power-up. Double-clicking the.VNE file will start the run-time system and execute the design – provided that one is present in the file.

86. SimPhonics, Inc. In the beginning there were computers, and the computer was programmed with ones and zeros. The programmer said, let us use text for these codes so that we can understand them better. So the assembler was created and the programmer was happy. Then the programmer said, let us program with words so that our programs are easier to understand. Hence, the compiler was born and the programmer smiled. Then the engineer said let us use this machine and program it with drawings of our ideas. Thus, V+ was born, the engineer rested, and the programmer went home. Closing Remarks
