L errorinfo: -- error messageIf the program is wrong, the TCL parser will give the error back to the application, and the program decides what to do with it. If there are no other measures, the error message will usually be printed on the screen, and this is errorinfo responsible for processing.L ErrorCode: -- error codeTCL provides another global variable, errorcode, which provides information about the error condition. The format is easily handled

The TCL interpreter manages all commands and global variables in groups. These groups are called namespaces, and commands and variables in one namespace do not affect another namespace. These namespaces are tree-organized, and one namespace command can be introduced into another namespace. The root of a namespace tree is the global namespace, which contains all the commands and variables that are not explicitly created in other namespaces.Any commands

Let's talk about the set command today. The SET command is used to assign values to a variable. It requires two parameters: variable name and variable value. In TCL, you do not need to follow the rules defined first and then used. The parser automatically creates a variable when the first value is assigned. After the value is assigned, you can use the dollar sign $ to add a variable name. Code highlighting produced by Actipro CodeHighlighter (freeware

The biggest advantage of Modelsim's Tcl is that it allows the entire simulation to run automatically, saving you from the trouble of performing various user interface control operations each time. With TCL, You can automatically create databases, map databases to physical directories, and compileSource code, Start the simulator, run the simulation and a series of other operations. The following describes t

　　expr is for Tcl-to-do math type operations. It takes all of its arguments ("2 + 2" for example) and evaluates the result as a Tcl "expression", and returns the value. Many commands expr use behind the scenes of order if to evaluate test expressions, such as, and loops. for tip: enclosing the arguments to in expr curly braces would result in faster code. So do expr{$i*10} instead of simplyexpr$i*
