i wanna to convert this code in vhdl

void main() { SerialPortInit(); /* Serial Communication – 9600-N-8-1 */

Send2Gsm("AT\r\n"); /* Transmit AT to the module – GSM Modem sends OK */ DelayS(2); /* 2 sec delay */

Send2Gsm("ATE0\r\n"); /* Echo Off */ DelayS(2); /* 2 sec delay */

Send2Gsm("AT+CMGF=1\r\n"); /* Switch to text mode */ DelayS(2); /* 2 sec delay */

Send2Gsm("AT+CMGS=\"+919447367176\"\r\n"); /* Send SMS to a cell number */ DelayS(2); /* 2 sec delay */

Send2Gsm("TEST DATA FROM RhydoLABZ-COCHIN"); /* Input SMS Data */ SerialTx(0x1a); /* Ctrl-Z indicates end of SMS */ DelayS(2); /* 2 sec delay */

while(1);

}

    process main
begin
    SerialPortInit; -- Serial Communication – 9600-N-8-1
    Send2Gsm("AT\r\n"); wait for 2 sec; --  Transmit AT to the module – GSM Modem sends OK */ DelayS(2); /* 2 sec delay */ 
    Send2Gsm("ATE0\r\n"); wait for 2 sec; -- Echo Off */ DelayS(2); /* 2 sec delay */
    Send2Gsm("AT+CMGF=1\r\n"); wait for 2 sec; -- Switch to text mode */ DelayS(2); /* 2 sec delay */
    Send2Gsm("AT+CMGS=\"+919447367176\"\r\n"); wait for 2 sec; -- Send SMS to a cell number */ DelayS(2); /* 2 sec delay */ 
    Send2Gsm("TEST DATA FROM RhydoLABZ-COCHIN"); wait for 2 sec; -- Input SMS Data */ SerialTx(0x1a); /* Ctrl-Z indicates end of SMS */ DelayS(2); /* 2 sec delay */ 
    wait; 
end process main;

    the code above cannot be synthesised as it contains a wait statement, which are used in simukation only.

    Hi,

    Please answer the following questions

    1. Why do you need to convert a C program into VHDL? Instead use NIOS II soft core processor to run the C code. That would save your time.

    2. Which FPGA are you targeting?

    Regards,

    Synthesis was not stated as a requirement. No need to make a simple request more complicated than actually requested.

    That wasnt the request - the OP wanted VHDL. KJ Posted Legal VHDL.

    coz i work in project called rfid and gsm mobile secuirty system and this based on fpga and vhdl

    fpga :altera DEO board

    My reply about the code not being synthesizable was intended as a note, just something to keep in mind. I should have stated this.

    If you don't want to use a softcore like NiosII you will have to think about which hardware components you need. I see an rs-232? and depending on the devices you use to send the GSM signals you will need to implement an interface for this as well.

    There can be two ways for the implementation:

    1. Design a NIOS II System with RS232 , SPI and other peripherals. Port your C code & libraries to NIOS II processor (though this may not be straight forward). Compile & generate the binaries.

    2. Complete RTL implementation

    For this you need to write VHDL code for UART, SPI protocol. Assuming this is a college project, implementing SPI & UART code in RTL can be mini project in itself. So divide the task & then integrate the modules where in top file you will have the Sequence of function calls (Algorithm for Security System).
