Maximum Values in Scripts

The SCL compiler, the OpenSTA run-time environment, and host system resources impose many limitations on Scripts. Exceeding these limits will be flagged by the compiler or the run-time environment. The maximum values (number, size, level, etc.) allowed in SCL source files are given in the following table:

attribute	maximum value
source line length (characters)	132
number of labels (per subroutine/main code)	255
number of timers	1020
number of variables	8000
number of global variables	8000
number of subroutines	255
number of parameters passed between Scripts	8
number of external data files referenced in Script	256
number of external data files open concurrently	10
character variable size (bytes)	65535
character constant/literal size (bytes)	65535
space available for Script values (Kbytes)	128
nesting level of array expressions	10
nesting level of conditional compilations	10
nesting level of IF/DO commands	100
nesting level of subroutines	10
