United StatesWrite VHDL code directly on your iPhone, iPad and iPod Touch! This app is ideal for learning and testing code snippets! VHDL (VHSIC Hardware Description Language) is a hardware description language used in electronic design automation to describe digital and mixed-signal systems such as field-programmable gate arrays and integrated circuits. VHDL can also be used as a general purpose parallel programming language. This app uses the open-source GHDL simulator (http://ghdl.free.fr). GHDL is a VHDL compiler that can execute (nearly) any VHDL program. GHDL is not a synthesis tool: you cannot create a netlist with GHDL (yet). Features: - Compile and run your program - View program output or detailed error - Custom keyboard for easy input of frequently used characters - Optimized for connecting with external physical/bluetooth keyboard - Advanced source code editor with syntax highlighting and line numbers - Open, save, import and share VHDL files. Limitations: - Internet connection is required for compilation - Maximum program running time is 20s - All entities should be have the same name as their files.
Works great simulates std_logic circuits just fine
I realized that it’s essential to limit simulation with ultimately a WAIT; statement including a clock generator with limited total time Here is a simple test setup beyond just text: Enjoy.. great job by the developer of the App and the original open source VHDL Compiler Designer ———————————————— -- Hello world program library IEEE; use IEEE.std_logic_1164.all; use std.textio.all; -- Imports the standard textio package. -- Defines a design entity, without any ports. entity hello is end hello; architecture behaviour of hello is signal index : integer:=0; signal clk : std_logic := '0'; begin process(clk) variable l : line; begin if(rising_edge(clk)) then write(l,String'("/")); writeline (output, l); end if; end process; process begin index <= index +1; clk <= not clk; wait for 1 ns; if index > 20 then wait; end if; end process; end behaviour;
