8 FAQ’s for Actel’s Antifuse FPGA Programming

Part number naming convention:

 ACT = initial release

 AACT = -1 (i.e. SM208PQ-ACTEL-1)

 BACT = -2 (i.e. SM208PQ-ACTEL-2)

6. Is there any limit on how many devices can be programmed with a

Silicon Sculptor adapter module?

Ans. Below is the Life cycles of Actel Silicon Sculptor modules:

Table 1: Silicon Sculptor Modules Life Cycles

Adapter Type

Typical Insertion cycle life

Module Base

> 50,000 insertions

Standard Pitch Socket Modules

10,000 to 20,000 insertions

BGA Sockets Modules

2,500 to 10,000 insertions

Carefully insert and remove the module from the programmer to avoid damage to the DIN connectors

(pins at the backside of the adapter module). Typical insertion cycles can be prolonged if the module

base and socket modules are properly cleaned and maintained. Handling and cleaning practices can

affect the number of insertions achieved.

In addition to maintaining the adapter module within the insertion limit, if you experience a lot of continuity

failures, then isolate the module and debug the issue. Please see details in Question 8 below.

7. Can I use the same module for different devices? For example, if I have

an SM84P-ACTEL-1 module, can I use it to program an A1020B-PL84 or

an A3265DX-PL84 device?

Ans. You can program the majority of Actel antifuse devices using the same package module on Silicon

Sculptor. However, some devices require a new revision or a different module for programming. For the

appropriate module needed to program each Actel device, refer to the module list at:

www.actel.com/products/hardware/program_debug/ss/modules.aspx.

8. How to debug continuity failures?

Ans. Isolate the adapter module if you experience a lot of continuity failures. Run blank check with

continuity check selected (see screen shot below) 20 times on a known blank device. If you experience

intermittent failures then the module may be defective. You should confirm this by running blank check 20

times with another adapter module and the same device. If you see consistent PASS then it is confirmed

that the subject adapter module is bad.
