Getting Started with Verilog-A, Verilog-AMS SImulation in Cadence

Hello, I would like to get started with Verilog-A and Verilog-A modeling in Cadence (for Data Converters and PLL systems). I have not used Cadence for these features yet, and do not know where to start. Can I use bmslib, ahdl lib elements ? What are the differences between the two ? Do I use the Verilog-A or Verilog-AMS views ? What are the differences between the two ? I was told to use the "ams" simulator in ADE vs. Spectre - is this correct ? If I use ams simulation option, do I use a Verilog-A or Verilog-AMS view of a block ? Is there a tutorial on doing Verilog-A or Verilog-AMS that I can access anywhere from Cadence or eleswhere ? Thank you.
