Since Windows Vista, Microsoft has offered 64 bit versions of Windows for 64 bit hardware and today almost every new machine will come with a 64 bit version of Windows. 64 bit Windows is still able to run 32 bit applications and up until now XJTAG has only been available as a 32 bit application. With the release of XJTAG 3.5, we are now offering a 64 bit version alongside the 32 bit version. […]
Until now, XJRunner tests have been limited to functions which have no input arguments and a single return argument (which returns the result). XJTAG v3.5 relaxes that restriction, allowing input in XJRunner tests, though there is still a requirement to have a single return argument for the result. […]
A boolean expression in XJEase is an expression that is considered to evaluate to either false or true. Boolean values are represented by an integer, where 0 is false and any other value is considered to be true. The standard Globals.xje that is included in all new projects has two constants defined, FALSE and TRUE. In XJEase we have three logical operators: NOT represented by !, AND represented by &&, and OR represented by || that operate on boolean values. […]
We have launched a new website today. As a result, existing logins for support and downloads will no longer work. Customers will need to create a new account, by clicking Sign in at the top and then clicking Register. You will immediately be able to submit support enquiries. Assuming you're in maintenance, XJTAG will activate [...]
We recently had to support a customer who was unable to run XJTAG 3.1 on an older PC. It turned out that the processor in the PC in question did not support SSE2 instructions. During the development of v3.1 we upgraded the compiler we use to build XJTAG and it now uses these instructions to speed up execution. SSE2 instructions were introduced with the Pentium 4 in 2001 and were supported in AMD processors with their Opteron and Athlon 64 processors from 2003 onwards.
One of the many netlist formats that XJTAG supports is EDIF 2, an open data exchange format that is widely supported. EDIF stores both netlist and schematic data, but XJTAG only uses the netlist data. It often seems like the obvious choice of format to export from your CAD tool to use in XJTAG. However, there are a number of problems that we have come across with EDIF netlists: […]
In XJTAG 2.6 we released a new .NET based XJRunner Integration API, replacing the old COM based API that was previously available. Version 2.6 and 2.7 continue to support the COM API, but do not install it by default. We recommend that any new development be done against the new .NET API. […]
A customer recently asked how to read some input from the user in XJEase. The next major release of XJTAG (probably numbered 2.4) will contain a new XJEase function INPUTBOX that makes doing this much simpler. In the meantime, I thought I might outline some code that accomplishes the same thing in the current version. […]
