Version History of SchemaHD

1.2.4

September 18, 2024

Corrected a problem that causes the application to close abnormally when operating the tool selection in the upper right corner of the drawing edit screen.

1.2.3

September 17, 2024

Fixed a problem that prevented Verilog export.

1.2.2

March 16, 2022

Bug Fix: The wheel shape of the picker, such as part selection, and the area to be tapped are now different.

1.2.1

October 7, 2021

Bug fix: Fixed an issue where picker shapes such as part selection were displayed in a different format from the wheel format on iOS 15.

1.2.0

September 27, 2021

New feature: PDF output of schematics is now available. This can be done from the design screen of the drawing. Bug fix: The icon for Logic and Bipolar part selection is not displayed.

1.1.1

September 4, 2021

Bug fix: Fixed a problem that did not cause an error when the interface of the instance's terminal was changed. Bug fix: Fixed a problem that caused switches and lamps to be the same as bit types when bipolar types were defined as subinterfaces in simulation. Bug fix: Fixed a problem in which the icon displayed when tapping the screen in the Combine, Separate operation to paste a part to the schematic was different from the icon of the part selected in the interface picker. Functionality improvement: To reduce the Combine icon size, the name of the output terminal has been changed to OUT. Functionality improvement: To reduce the icon size of Separate, the name of the input terminal has been changed to IN.

1.1.0

August 31, 2021

New feature: Bipolar type is now supported. It is now possible to know the end of an operation, which was not possible with combinational circuits using bit types. The simulation will also change color depending on the bipolar value. For details, see "Bit to Bipolar Type" in the menu at the top of the support page. https://schemahd.com/en/bipolar.html Improved functionality: The toolbar in the Drawing Design screen has been moved to the top of the properties on the right side. Feature improvement: JSON export and clone generation have been moved to Drawing List and Interface List. Functionality improvement: Library and Trash lists are now sorted. Functionality improvement: Changed the design of the buttons.

1.0.2

August 23, 2021

Bug Fix: Fixed the problem that the test point of the part pasted on the drawing is displayed on the picker when wiring. Bug Fix: Fixed a problem that prevented the connection to the terminal if there was an unconnected terminal above the selected part during wiring.

1.0.1

August 13, 2021

Bug fix: Fixed an issue where the initial number of bits is set to zero when creating a new interface.

Description of SchemaHD

FPGAs can dynamically generate logic circuits by means of configuration bit streams generated by languages such as Verilog and VHDL. The generated logic circuit cannot be changed by communication data. Therefore, it is very safe and cannot be attacked by hacking, which is a problem with CPUs, to execute arbitrary commands. In addition, the generated logic circuits are all running simultaneously, so the highest performance parallel processing is being performed. It can also generate logic circuits using configuration bitstreams at very high speed. Most of the processing that can be done by the CPU can be done by the FPGA alone. With advanced security and the highest performace, FPGAs are the perfect device for the modern age. However, it takes a lot of effort to learn languages such as Verilog and VHDL. There are other methods such as high-level synthesis from C/C++, but they require a lot of adjustments such as #pragma, and do not maximize the capabilities of the FPGA. Schematics, not programming languages, are needed to maximize the capabilities of FPGAs and to further improve developer productivity. Schematics allow you to grasp the whole picture at a glance, and can perfectly represent parallel processing. SchemaHD is to draw a circuit diagram of a logic circuit, and it's possible to do generation of Verilog HDL and a simulation. A made circuit diagram can be used by a different circuit diagram immediately. You can also install wiring easily by touch operation. A concept of interface is adopted as a terminal, so something structured of a AXI bus can also be used. A terminal it's also possible to distinguish sound argument reason, negative logic and characteristic wiring of a clock and a reset by interface, and which is different in interface, they don't seem able to connect, it is. You can input and output as a JSON file, so the made circuit diagram and interface are also capable of cooperation with other application. Verilog HDL generated from a circuit diagram contains a comment of a terminal name and an instance name, so it's capable of the correspondence which is at the time of problem occurrence. A network connection isn't needed, so it's also effective in information leak prevention. A simple simulation is offered in the present, but it's expected to enhance it early.

Unintelligble
Cool concept, but unable to use as the directions are intelligible and there are no examples. It appears the ‘help file” was translated via computer. Unable to figure out how to create and simulate file or to export verilog. UI needs work.
Has potential to be useful if author provided genuine English translation with tutorial and sample templates. I would love to try an updated version that addresses my concerns.

Export Verilog file seems not working
Very interesting app. I’m trying to understand how it works, but it seems that clicking the export Verilog buttons doesn’t do anything.
