Questions and Answers


Question: I would like to know whether it is possible to keep previous analysis plots open for comparison with the latest analysis plot.

Answer: Yes it is possible to save and recall curves for later display. After the run, press F10 to access the Plot Properties dialog box. Click on the Save Curves tab. Select which curve you want to save and press the Save button. In general, you can save any curve that was plotted or printed to numeric output to a User file.

Waveforms contained in User files can be plotted on subsequent runs by adding a new waveform line in the Analysis Limits (F9) dialog box, then right clicking the mouse in the Y expression field and from the Curves option, selecting a previously saved curve for plotting.

These curves may also be assigned to a User source in the schematic and used to provide a voltage waveform for the source.

Question: In Micro-Cap 6 I used to be able to terminate text entry by pressing the Enter key. Now that just moves the cursor to the next line. To quit I have to click on the OK button. What's going on?

Answer: When entering text in Micro-Cap 6, you simply type the text, then press the Enter key because the Enter key means quit the text dialog box and thus terminate the text. Adding a line feed to the text is done by pressing the CTRL key and the Enter key simultaneously.

When entering text in Micro-Cap 7, you simply type the text and press the Enter key to add line feeds to the text. To terminate the text, you exit the dialog box by clicking on the OK button. Alternatively, you can exit by pressing the Tab key to move the focus to the OK button, then pressing the Enter key.

To summarize the keys are as follows:

For Micro-Cap 6
For the text line feed use CTRL+Enter.
To exit the dialog box use Enter, or click OK.

For Micro-Cap 7
For the text line feed use Enter.
To exit the dialog box use Tab, then Enter or click OK.

Question: I am trying to install Micro-Cap 6 in a machine with Windows XP. I get the following error: "Can't find NetHasp Server". Any suggestions would be appreciated.

Answer: The old MC5 / MC6 HINSTALL program that installs the license manager will not work with Windows XP. The MC5/MC6 programs work fine. It is just the license manager that doesn't work. To correct this problem download the latest HINSTALL.ZIP file from Download section of our web site (www.spectrum-soft.com), extract the HINSTALL.EXE program and run it as shown on the web site instructions. This will remove the old manager and install a new one compatible with the idiosyncrasies of the XP system.
