Hi, everyone. I am the first time asking the questions here.

I want to declare a double array parameter.

However, I meet an error as below.

Can someone help me?

Thank you very much.

error (10709): systemverilog error at command_lookup.v(87): parameter with complex/aggregate value must have a type

	parameter  command = {		// Clear the screen and set cursor position to home

Change your declaration to

parameter bit command = { // Clear the screen and set cursor position to home

It is a good idea for any parameter declaration.

Thank you very much. I try it.

However, I meet another error.

Error (10161): Verilog HDL error at command_lookup.v(87): object "bit" is not declared. Verify the object name is correct. If the name is correct, declare the object.

Do you know what it is?

have you saved the file with .sv extension? it is trying to compile it as verilog, not SV
