This README file describes MXIC MX66-series verilog behavioral
model. It consists of several sections as follows:
1. Overview
2. Files
3. Usage
1. Overview
---------------------------------
The MX66-series verilog behavioral model is able to assist you to integrate
MX66-series flash product at early simulation stage. There are helpful tips
and notes in this READEME file. Please read this file before applying this
behavioral model.
2. Files
---------------------------------
The following files will be available after extracting the zipped file
(or other compression format):
MX66XXXX\
|- README.txt
|- MX66XXXX.v
The naming rule of MX66-series verilog behavioral model is as follows:
MX66XXXX.v:
---- -
| |--> v. Verilog source code.
|
|------> Flash's part name. Ex: MX66L51235F.
3. Usage
---------------------------------
The MX66-series behavioral model can be applied directly at the simulation
stage. Please connect correct wires to top module of this model according to
flash datasheet. This is not a synthesizable verilog code but for functional
simulation only. Please be aware of the followings:
a. The model can load initial flash data from a file by parameter definition.
Users can change Init_File parameter with initial data's file name. Default
file name is "none" and initial flash data is "FF".
parameter Init_File = "xxx";
where xxx: initial flash data file name, default is "none".
b. Note that the behavioral model needs to wait for power setup time, tVSL.
After tVSL time, chip can be fully accessible. If tPUW has defined, read
instruction and write instruction can be accepted by flash after tVSL and
tPUW time. The tPUW is longer than tVSL.
tPUW is not defined:
| |---------tVSL---------|
|____________________________|
| |
Power on Read/Write enable
tPUW is defined:
| |----------tPUW------------|
| |--tVSL--| |
|_____________________________|
| | |
Power on Read enable Write enable
c. More than one value (min. typ. max. value) is defined for some AC parameters
in the datasheet. But only one of them is selected in the behavioral model,
e.g. program and erase cycle time is the typical value. For detailed
information of the parameters, please refer to the datasheet and feel free
to contact Macronix.
