Description
Write 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.
What’s New
Version 2.2.1
Fixes a crash when opening files
Ratings and Reviews
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;
