JLS Startup File

The JLS startup file is used to force various circuit properties when JLS is run in batch mode. The startup file is ignored if JLS is started up in interractive mode.

Specify default propagation delays for any or all element types.
```
    TYPE type PROPDELAY delay
```
where type is one of AndGate, OrGate, NotGate, XorGate, NandGate, NorGate, DelayGate, TriState, Register, Memory, MUX, Adder, Decoder, and delay is a positive integer.
Make all elements in the circuit being loaded unwatched.
```
    CLEAR WATCHES
```
Remove all probes from the circuit being loaded.
```
    CLEAR PROBES
```
Reset all propagation delays to their default values in the circuit being loaded.
```
    RESET PROPDELAYS
```
Specify that specifically named elements (registers, memories, etc.) be watched or not.
```
    ELEMENT name WATCHED true/false
```
where name is the name of an element in the circuit and true/false is either the word true or the word false. If name is an element in a subcircuit, then the sequence of subcircuit names starting with subcircuit in the main circuit must be used, with periods between the names. For example, if the main circuit has a subcircuit called "cache" and the cache subcircuit has a subcircuit called "control" and the control subcircuit has a register element called "tag", then the name of the tag register is cache.control.tag.
Specify propagation delays for specifically named elements (registers, memories, etc.).
```
    ELEMENT name PROPDELAY value
```
where name is the name of an element in the circuit and value is the propagation delay (or access time in the case of a memory element) and is a positive integer. If name is an element in a subcircuit, then it must be qualified as in the previous specification.
Specify initial values for specifically named registers.
```
    ELEMENT name INITIALLY value
```
where name is the name of a register element in the circuit and value is the initial value for that register, a positive integer. If name is an element in a subcircuit, then it must be qualified as in the previous specification.
Specify the file name for specificially named memories to read their initial contents from.
```
    ELEMENT name FILENAME filename
```
where name is the name of a memory element in the circuit and filename is the name of the file to read initial memory contents from when simulation begins. This overrides any builtin memory values. If name is an element in a subcircuit, then it must be qualified as in the previous specification.

The parameter file is read in order and each specification is processed in order. For example, to make exactly one register (say PC) be watched and everything else not watched, first specify that all elements be unwatched, then make the PC watched.

Note that all parameter file information is case sensitive. Otherwise no special formatting is required, other than words and numbers must be separated by white space (one or more spaces, tabs and/or new lines). If any errors are encountered when JLS reads the parameter file, an error message is printed and JLS terminates immediately.
