DVM - Design Verification Module

Testplans

Testplan files are tab-separated text files with a .testplan extension and the following rules:

• Blank lines are ignored.
• Lines starting with an asterisk (*) are considered comments and are ignored.
• Inline comments are not supported; that is, you can comment out an entire line, but not a portion of a line.
• Each non-blank, non-comment line in the testplan describes a set of test conditions for a single test. Each column performs some action during the test.
• Any column can have an empty cell in a row but the behavior is different for columns with function headings.

  • If the column heading is a function, such as Var(vout , 1.2), DVM uses the default value, in this case 1.2.

  • If the column heading is not a function, DVM makes no changes for that column where a cell is empty.

Testplan Content

• Without a header row, each field must include a prefix to indicate the desired action. For example:

  simulator: simetrix	include: include1.txt
  simulator: simplis	include: include2.txt

• With a header row you can avoid prefixing each field by including a specially formatted comment line with the prefix that functions as a column  heading.

  *?@ column1	column2	column3	column4
  value1	value2	value3	value4
  value5	value6	value7	value8

  Note: When you use the create a testplan with the format above, the simulator regenerates the information into the format shown below, which is the equivalent structure that you would use without the header row.

  column1: value1	column2: value2	column3: value3	column4: value4
  column1: value5	column2: value6	column3: value7	column4: value8
