17.6 Parameters from Other Scripts

Parameter declarations can be taken (imported) from other script files by using the declaration

  params from SCRIPT [except NAMES] [default NAME = VALUE ...]

All parameter (but not result) declarations from the given script will be used as if they had been declared in the importing script.

The optional except clause will exclude one or more comma-separated parameters.

Example: if the script a.simics contains:

  decl {
    params from "b.simics" except y
    param x : int
    result r : string
  }

and b.simics contains:

  decl {
    param y : int = 10
    param z : bool = TRUE
    result s : string
  }

then a.simics will behave as if it had been written:

  decl {
    param z : bool = TRUE
    param x : int
    result r : string
  }

The default value of imported parameters can be overridden by adding default clauses. Example:

  params from "hardware-setup.simics"
    default ram_size = 256
    default cpu_freq = 3.58e6

There is also a substitute declaration that is reserved for Simics internal use.
