This ZIP file contains two files that will update the ECS symbols in a project directory. It also contains a readme.txt file that explains their usage.
Alternatively, for small designs with relatively few symbols, you may update each symbol manually by following these steps:
1. Select the nets that were named in the error message. 2. Trace the net to any sub-block and select the sub-block. 3. Right-click on the block and select "Edit Symbol". 4. In the new symbol window, select the symbol. 5. Right-click on the symbol and select "Object Properties". 6. In the Category window, expand the pins and select the input pins. 7. In the Symbol Attribute window, you will notice that no polarity is assigned to the pins. 8. Select all the input pins that do not have polarity assigned. 9. Click New, and enter "Polarity" for attribute name and "IN" for attribute value. 10. Select "OK", save, and update the symbol.
