Note: This file has been created automatically from a Verilog-AMS input file using adms and xml translater vlatomml.xml . The main purpose of the translater is to help debugging adms and simplifying the process of documenting compact devices. The rendering of the output can greatly be improved. Any comments/helps highly appreciated. [r29173]
