SRAM-based FPGAs are non-volatile devices. Upon powerup, They are required to be programmed from an external source. This procedure allows anyone to easily monitor the bit-stream, and clone the device. The problem then becomes how can you effectively protect your intellectual property from others in an architecture where the part is externally programmed?

pb datawindow 技巧 例子： 使DataWindow列只能追加不能修改 如何使DataWindow中的數據只能追加新記錄而不能修改，利用 Column 的 protect 屬性可以很方便的做到這一點，方法如下： 將每一列的 protect 屬性設置為： If( IsRowNew(), 0, 1) ) 在 PowerScript 中可以動態修改 protect 屬性： dw_1.Modify("column_name_here.protect= 1~tIf(IsRowNew(),0,1) ") 這樣，DataWindow 中只有新追加的記錄可修改，而其他記錄是只讀的。

The W78E58B is an 8-bit microcontroller which has an in-system programmable Flash EPROM for firmware updating. The instruction set of the W78E58B is fully compatible with the standard 8052. The W78E58B contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary ROM 512 bytes of on-chip RAM four 8-bit bi-directional and bit-addressable I/O ports an additional 4- bit port P4 three 16-bit timer/counters a serial port. These peripherals are supported by a eight sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the W78E58B allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security

Electrostatic discharge (ESD) is one of the most prevalent threats to the reliability of electronic components. It is an event in which a finite amount of charge is trans- ferred from one object (i.e., human body) to another (i.e., microchip). This process can result in a very high current passing through the microchip within a very short period of time, and, hence, more than 35% of chip damages can be attributed to an ESD-related event. As such, designing on-chip ESD structures to protect integrated circuits against the ESD stresses is a high priority in the semiconductor industry.

The field of cyber security, or information security, or information assurance, depending on your preference, is an interdisciplinary one. It is part computer science, part statistics, part psychology, part law, and a part of many other fields. Moreover, any cyber security practi- tioner needs to know what he or she is protecting and where to pri- oritize. Just as someone should not spend $100 to protect something worth $10, one cannot be blind to the other disciplines.
