   transistors, two operational amplifiers, or 65 digital primitive 
   devices, or a combination thereof, and 10 ideal transmission lines 
   with not more than 4 non-ideal lines (lossy lines using RLGC 
   parameters) and 4 coupled lines.
 - Device characterization is limited to diodes
 - Interactive stimulus generation program is limited to sine waves 
   (analog) and clocks (digital)
 - Sample library of 35 analog and 130 digital parts

MicroSim PSpice Optimizer:
 - Requires MicroSim PSpice A/D with Schematics evaluation package 
 - Limited to one goal, one parameter, and one constraint

MicroSim PLSyn:
 - Reduced symbol library set
 - No integrated symbol editor
 - PLD simulation only
 - No support for discrete digital parts
 - Simulations may only be started via the Analysis/simulate command in 
   Schematics
 - The simulation model library is limited to PLSYN_IO_xxx models 
 - Fitting is limited to the AMD MACH231 architecture

MicroSim Probe:
 - Can't read a production data file, or a .csdf data file


How to Install the Windows Evaluation Versions
============================================== 

1.  Create a temporary directory on the hard drive.

	C:\>md temp

2.  Change to the temporary directory.

	C:\>cd temp
	C:\temp>

3.  Download the complete evaluation version(s) (80dlabe.exe) 
    OR the 13 pieces that make up the evaluation version
    (80dlep1.exe, 80dlep2.exe, 80dlep3.exe, through 80dlep13.exe) into
    the temporary directory that was just created.

4.  Type the name(s) of the self-extracting files. 

	C:\temp>80dlabe.exe -d     (Complete Evaluation Version)

    OR

	C:\temp>80dlep1.exe -d     (Evaluation Version Part 1)
	C:\temp>80dlep2.exe -d     (Evaluation Version Part 2)
	C:\temp>80dlep3.exe -d     (Evaluation Version Part 3)
	C:\temp>80dlep4.exe -d     (Evaluation Version Part 4)
	C:\temp>80dlep5.exe -d     (Evaluation Version Part 5)
	C:\temp>80dlep6.exe -d     (Evaluation Version Part 6)
	C:\temp>80dlep7.exe -d     (Evaluation Version Part 7)
	C:\temp>80dlep8.exe -d     (Evaluation Version Part 8)
	C:\temp>80dlep9.exe -d     (Evaluation Version Part 9)
	C:\temp>80dlep10.exe -d    (Evaluation Version Part 10)
	C:\temp>80dlep11.exe -d    (Evaluation Version Part 11)
	C:\temp>80dlep12.exe -d    (Evaluation Version Part 12)
	C:\temp>80dlep13.exe -d    (Evaluation Version Part 13)


5.  To install the evaluation version, from Windows (95 or NT) run 
    the SETUP.EXE program located in the temporary directory above (or 
    from the DISK1 directory).
