The advanced symbol wizard is used to quickly create symbols for IC type chips. The advanced symbol wizard does not distinguish the types of symbols. It only requires the user to fill in the corresponding data in the template, and the system can generate symbols according to the filled data.
Operation steps: Top Menu - Tools - Advanced Symbol Wizard
Export the template in the template popup
Open the template with “office” “WPS”
- Part: represents the sub-library page of the symbol, not the pin number;
Side (direction): the direction of the pin, L represents the left side, T represents the upper side, R represents the right side, and B is the lower side;
Order (serial number): Determine the positional relationship of the pins in different directions;
Pin Name: the name of the pin;
Pin Type: Set whether the pin is input (IN) or output (OUT) type;
Pin Number: the number of the pin;
Pin Reverse (non-pin): whether it is a pin type;
Here we use the LQFP type notation for this 32-pin series as an example:
Here we fill in his parts first, because we only have one part without the sub-library symbol, so fill in 1. If there is a sub-library, you need to install the last 1 digit of the part name in the left panel to fill in accordingly.
Next, enter the direction of the pins. In the chip picture, it can be seen that No. 1-8 is on the left, here you need to input L to represent left, No. 9-10 pins are on the bottom, input B to represent down, 17- Pin 24 is on the right, input R represents right, pins 25 - 32 represent top, and input T represents top.
Then continue to enter the serial number of the pin, the rules for the arrangement of the serial number: the pin No. 1 in the row of pins on the left corresponds to the pin No. 24 on the right, so the pin No. 24 corresponds to the pin 1, so the pin No. 24 needs to be input 1. You can only fill in the order of two directions, and the order of different directions cannot be arranged in sequence. For example, the number of pins on the left is 8, then the serial number is in place 1-8, and the number of pins on the bottom is also 8, the serial number needs to be arranged in the center, and the serial number of the left pin cannot be followed, and it needs to be rearranged.
Next, enter the name of the pin according to the data in the figure
The input pin type is uniformly input IN here. The pin type will not affect the footprint. Users can look at the data sheet of the chip for input. The delay will not be introduced here.
input pin number
Enter NO for the last item, because this chip is a pin, not a non-pin
The overall data has been entered, the next step is to import it, open the Advanced Symbol Wizard, and click Import.
After importing, you can see the value just entered in the template, click OK to generate the symbol.
