1. Why the final generated PCB layout does not match the schematic
A: This situation can easily happen. Indeed, it is obviously connected on the schematic diagram, because the drawing line does not meet the specifications. As a result, they are not connected in the generated netlist.
2. There are many previous file lists in the toolbar, which are very long and look messy. I deleted the original file, where can I delete it.
A: There is a Protel configuration file Client99.ini in the \Windows directory, which can be opened with a text editor, find the [Closed Files List] column, delete all the content belonging to this column, save it and exit.
3. Why the diodes and transistors in the schematic diagram cannot find the pins when they are loaded into the netlist of the PCB circuit board
Answer: The reason is that the pin names in SCH and PCB are defined differently. Especially the A, K-1, 2 and E, B, C-1, 2, 3 of the two and three-pole transistors, change the network table by yourself, and don't make a mistake in the pin order.
4. How to find out the hidden DESIGNOR component number in protel99
A: In SCH, double-click the component, select Hidden Fields and Field Names in the dialog box, then double-click the serial number Text and parameter Type respectively, and uncheck the Hide. Finally, double-click the component, and uncheck the Hidden Fields and Field Names in the dialog box.
5. How to use "global function" in protel99 to encapsulate all components without encapsulation
Answer: Press the Global key, for example: to change the package of Res2, remove * in Desigator, fill in Res2, tick in Footprint of Copy Attribute, and select All primitives in Change Scope
6. When installing PROTEL99, I was not asked to enter LICENSE NUMBER. Now PROTEL99 can be used, but there is a problem. How to enter LICENSE NUMBER?
Answer: First of all, it is recommended that you reinstall protel99se. Your question: Click the arrow on the left side of the protel99 menu bar, select security, select PCB SCH Route respectively, click un-lock, press Add and then fill in the password.
