Naming Conventions
Node and Element Identification
o Either Names or Numbers, no delimiters (e.g. src, n3, 11, …) o 0 is ALWAYS Ground o Trailing Alphabetic Character are ignored in Node Number (e.g. 5A = 5B = 5)
o Ground may be 0, GND, !GND
o All nodes are assumed to be local o Node names can be across all subcircuits by .GLOBAL statement (e.g. .GLOBAL VDD VSS)

Format Conventions
o A line may be continued by entering a plus sign('+') in column 1 of the following line.
o Quotation marks must be used to specify an algebraic equation. Both single(„ ‟) and double(“ ”) quotation marks can be used. (e.g. J = „ A+B*C ‟, K = “2*J”)
