Problem using ULP

[adreeshmitra]

I wrote a simple code in ULP to make a simple pcb using resistors and capacitors (I have generated the code by feeding the ULP documentation to Chatgpt). But the code is not running. It will be great if someone debug the code for me. 

The code is like this:

#usage "This ULP creates a simple PCB layout with basic elements."

board(B) {

// Set grid and dimensions

B.grid.on = 1;

B.grid.unit = GRID_UNIT_MM; // Set unit to millimeters

B.grid.distance = 0.1; // Grid distance 0.1 mm

// Add a few elements (Resistor and Capacitor)

B.elements(E) {

if (E.name == "") { // Add resistor if element slot is empty

E.package = "R-EU_0207"; // Add a resistor package (make sure this exists in the library)

E.name = "R1"; // Assign a name to the element

E.x = 10; // X coordinate of the element in mm

E.y = 15; // Y coordinate of the element in mm

}

if (E.name == "") { // Add capacitor if element slot is empty

E.package = "C-EU0603"; // Add a capacitor package (make sure this exists in the library)

E.name = "C1"; // Assign a name to the element

E.x = 20; // X coordinate of the element in mm

E.y = 15; // Y coordinate of the element in mm

}

}

// Create a signal for wiring

B.signals(S) {

if (S.name == "") { // Create a new signal for wiring

S.name = "Net1";

}

S.wires(W) {

W.x1 = 10; W.y1 = 15; // Start point of wire

W.x2 = 20; W.y2 = 15; // End point of wire

W.width = 0.5; // Wire width in mm

W.layer = LAYER_TOP; // Place the wire on the top layer

}

}

printf("Simple PCB layout generated with components and basic wiring.");

}

exit(0); // Exit ULP

I have also attached the documentation that I have used.

So I guess my first question is why you would want a script to do this?

I've never seen a ULP attempt to set values within datatypes like that so I'm pretty sure they are read only.

If you wanted a simple script to place parts you could easily put a series of ADD commands in a .scr file. You can stack up as many editor commands as you want using the script file. Check the editor commands section within the help section.

Example to place the parts:

ADD R-EU_0207 R1 R0 (10 15);

ADD C-EU0603 C1 R0 (20 15);
