Netcad Viewer
Savage Doherty
Last year, a professor from the university said that he wanted to install NetCAD on his computer in order to view the files with * .ncz extension, but he could not find the appropriate NetCAD installation file. Today, a friend of mine, who is also a geological engineer, stated that he made a lot of research on the internet to view files with * .ncz extension in the field, but he could not find a suitable software. I think one of the biggest shortcomings of NetCAD at this point is the lack of a viewer application to view files with * .ncz extensions or the lack of a restricted version (such as no recording or output). In fact, people are first looking for applications called NetCAD viewer or ncz viewer, but somehow they cannot find what they are looking for. However, there are several more successful map cad software that is equivalent to NetCAD in the market and unlike NetCAD, there are demo or limited versions of these software that can display files with * .ncz extension.
The first of these, and GeoCAD, which I have used for a long time. Although GeoCAD has a long history, it had a difficult time in 2000, when 2 developer engineers died in a fatal traffic accident. However, GeoCAD, whose development process continues, besides having a very fast and functional structure, it can successfully run many file formats including * .ncz. Although GeoCAD is still commercially available, you can download the pro version of the software for free and install it directly. In this way, you can easily view files with * .ncz extension as a demo without paying a license fee. You can also save your files with a * .cad extension, and create projects that you can store in this extension (click here for detailed information about GeoCAD software, click here to download GeoCAD Pro for free).
Secondly; BelsisCAD, owned by the rapidly growing Belsis Company. Belsis Firm shows up in two areas, BelsisGIS and BelsisMIS, as well as BelsisCAD cad software. With the BelsisCAD Viewer, which is available free of charge by Belsis Company, * .ncz extension files can be viewed. You can also use save and print operations although it has very few functions. (Click here to get detailed information about BelsisCAD Viewer software and here to download BelsisCAD Viewer for free).
Both of the above mentioned cad software are quite successful in terms of viewing files with * .ncz extensions. But the point that should not be forgotten; The * .ncz extension file format belongs to NetCAD software, and therefore software other than NetCAD may not be able to perform this file format with 100% accuracy.
VS 2017: by default the help viewer is not installed. To install and use the CadLib help files, first install the VS help viewer, and Set 'Help Preference' to 'Launch in Help Viewer'. See here for an howto.
Both C# and VB sample solutions are provided. A basic viewer example is included so you can test view the DWG and DXF files you have created with the library. Also a DWG/DXF to image converter example is included and an example DWG/DXF writing program.
A high quality configurable PDF converter is included, that optionally creates searchable PDF files. An example console application is included (see the export example) that demonstrates the conversion from an AutoCAD DWG or DXF file to PDF.
Example solutions written in C# and VB.NET show how to add more advanced features like zooming, panning and picking. Samples are included that demonstrate use with Windows Forms, WPF, OpenGL and ASP.NET 4.0.
VS 2017: by default the help viewer is not installed. To install and use the CadLib help files, first install the VS help viewer, and Set 'Help Preference' to 'Launch in Help Viewer'. See here for an howto.
Both apps allow users to view, edit, share and create 2D CAD drawings. AutoCAD web app is accessed entirely online in a web browser on any computer. AutoCAD mobile app is included with AutoCAD and AutoCAD LT and provides similar features on iPhone and Android devices.
For stakeholders who only need file-viewing access, we offer free viewers without a subscription. If you're transitioning to named user, make sure that you take advantage of the trade-in offers available to you.
A parallel link interface is usually a bus with many data sources and/or destinations. You need to evaluate clock to data timing for each combination of driver and receiver on the parallel interface. It is also necessary to examine the shape of the waveform for each such combination. Problems such as inadequate amplitude, inadequate slew rate, or ringing can cause unreliable data transfer while problems such as overshoot can cause premature failure.
Each interface design must be evaluated both before and after the system and PC boards are designed. The pre-layout analysis is required if the design is to have any chance of working, and the post-layout analysis is required to make sure nothing was missed in the PC board design process. The net result is that there is usually a massive number of possibilities to analyze. These possibilities are the compounded combination of every combination of driver and receiver, every phase of the interface protocol, semiconductor process corners, PC board process corners separately for each layer of each PC board, passive component value, power supply voltages, temperature, and pre-layout and post-layout analysis. Failure to evaluate each and every one of these combinations increases the probability that problems will be identified much later in the design cycle, when correcting them is much more expensive.
The Parallel Link Designer app automates the running of the simulations by providing a graphical environment to set up the simulations and a standardized way in which to organize the model libraries. You can sift through the mass of data to identify information which is critical to the design in several ways:
A separate spreadsheet is provided for waveform analyses and timing analyses. Each such spreadsheet organizes the data from summary information to the details of individual cases, thus making it practical to find detailed information about individual failing or marginal cases.
A waveform viewer makes it convenient to examine results graphically. Separate display panels are provided for waveforms and tabular results. Waveforms can be viewed in either the time domain or the frequency domain. Tabular results are presented in scatter plot format.
Transfer nets are common to both pre-layout analysis and post-layout verification. In pre-layout analysis, each sheet has an associated transfer net with the same name as the sheet. In post-layout verification, extended nets are assigned to transfer nets.
In pre-layout analysis, each transfer net is described on a separate schematic sheet and is simulated in a separate simulation run. The circuit element values in a transfer net schematic can be parameterized so that many variations can be evaluated without having to change the schematic. Also, a transfer net schematic can contain crosstalk interferers, so that the analysis of the transfer net can be complete.
In post-layout analysis, each net on a PCB is called a CAD net. CAD nets can be combined with drivers, receivers, packages, discrete components and connector pins to form an extended net. An extended net contains designators and reaches from one IC to another. Extended nets can also traverse multiple PCBs. The Parallel Link Designer app provides convenient mechanisms for identifying extended nets and assigning them to transfer nets for all major PCB flows.
One of the advantages of the transfer net concept is that transfer nets can be re-used without modification from one phase of a project to another, or between projects. For example, if transfer nets were defined during the pre-layout phase of a project, then those definitions can be re-used without modification during the post-layout phase. Conversely, if a transfer net has been defined in the post-layout phase, it can be re-used directly in a pre-layout analysis
There are usually a number of different types of data associated with a given component, including electrical data such as HSPICE or IBIS models, timing models, and physical data such as CAD part number and pinout. For each component, all of this data is kept together in a Part, and every designator in a schematic must have a Part.
The Parallel Link Designer app includes a 2D field solver which can be used to create accurate models of lossy transmission lines. There are well defined places to put libraries either for a single project or to be shared among many projects. The same library elements are used in pre-layout and post-layout analysis.
