Questions and Answers - Summer 2014

 

Question: Question: I am having trouble installing my new Micro-Cap 11. It seems to install the main Micro-Cap files but has trouble even launching the HASP driver (haspdinst.exe). When it finishes with an error message, I can see the Micro-Cap folder but I can't run Micro-Cap because it says it can't find the key.

Answer: There are several possible problems but the most likely answer is that you are probably installing under non-administrator (admin) status and the OS may be setup to require admin status in order to install the HASP driver (haspdinst.exe). The HASP driver adds a device driver so it has more potential for causing security problems, so some organizations arrange the OS to require admin status to do this.

Try gaining admin status and retry the whole installation again. If you install outside the Program Files folder (which we strongly recommend) you shouldn't need to run Micro-Cap under admin status, but you probably need to install it that way.

Question: I want to generate a PADS netlist. I want to control the footprint name using the PADS box in the package editor. This is working OK for most parts, but I have a problem with resistors and capacitors. I have to create a part with a model for the various resistor and capacitor footprints I want to use. How can I create a library for my custom resistors so I can make a part so I can associate a PADS footprint with the part?

Answer: Create a new resistor part type in the Component library and then create a listing in the Package library defining its package type. When you place this resistor in a schematic, MC11 automatically assigns its PACKAGE attribute using the Package library entry. The PADS netlist is generated using the part's PACKAGE attribute shown in the Attribute dialog box.
