It allows you to navigate the dump as it is being written to the pipe and watch the simulation in real time. Techniques like named pipes and shared memory proxies are used to facilitate the same. Value change dump (VCD) is the most preferred format for saving simulation dump files, while some companies have their own proprietary formats that include extra details depending on the developer. In the industry, though, operation is not as dynamic, as engineers run batches of simulations including all possible sets before running the waveforms to check for consistency. Not only does this help in individual assessment of signals but it also shows the effect of signals interacting with each other in the circuit. Traditionally, in integrated circuit design, waveform viewers are typically used in conjunction with a simulator. Scrolling and other GUI manipulations can be performed in lockstep across both sessions. 2: Demonstrating application integration with Mac OSX/QuartzĪnother important feature is called TwinWave, which is a GTKPlug helping you manage two or more sessions of GTKWave in either a single window or in two separate windows. This can be enabled because of the availability of TCL scripting and call-back capability. #Vcd waveform viewer for mac codeGTKWave has provisions in its code for remote control by other applications. If, for example, you are working on a synthesised netlist, then you will find that this tree-searching feature helps you filter signal names at the highest level, saving you a lot of time. The filter allows you to filter a specific sect of signals that you might want to investigate further. It has a top tree selection box, signals box and POSIX regular expression filter. This is the most used search requester, as it can be directly embedded onto GTKWave versions 2.4 and above. In this format, in order to append, replace or insert, you need to select individual ones, otherwise the selected parent and children will be acted upon. ![]() It contains the current hierarchy as well as the children box, which contains all signals in the immediate hierarchy below the searched parent term. In essence, it is the same as the file explorer for any operating system. Hierarchy search, as the name suggests, provides a view of the hierarchy in a format similar to the current working directory. After selecting, there are options to append, replace or insert, as required. ![]() These can be controlled and manipulated by either dragging one or more into gtkwave viewer. If a signal is found matching the string, it is listed in Matches section. In this mode, the search requester accepts a search string as a regular expression. As such, it is home to three different signal-searching modes, namely, signal search, hierarchy and tree. GTKWave is designed to process a host of signals at once. 1: GTKWave running under Linux Multiple signal processing ![]() Functions like file conversion, RTL parsing and other data-manipulation operations are performed by the aforementioned helper applications. To annotate the code at this level, invoke it by gtkwave. It allows for viewing of RTL at file and module levels. Rtlbrowse is used to view and navigate through RTL source code that has been passed and processed into a stems file by vermin-another helper application. For hard copies, you can export the results in PostScript and FrameMaker output. #Vcd waveform viewer for mac fullIf a full simulation dump is input, then it can help in data visualisation of analogue and digital data, while allowing for search operations, temporal manipulations and save partial results. Gtkwave is the name of the primary tool under use, which helps with all major visualisations. There are a bunch of applications under the hood that assist in the working while working themselves under independent situations. GTKWave tool has two separate but interlocking tools, that is, gtkwave viewer and rtlbrowse. ![]()
