AttributeError: 'List' object has no attribute 'vhd'...I m getting this error while i want to make a circuit that does the convolution of square wave and triangular wave ...Please suggest me any modifications in this code so that i will get the desired op

from myhdl import *
import matplotlib.pyplot as plt

from mmm import sig_square,sig_triag
@block
def sin_1( sel,out):
    sig1=tuple([(sig_square(x//100)) for x in range(1000)])
    sig2=tuple([(sig_triag(x//100)) for x in range(200)])
    
    @always_comb
    def hdl_1():
        
        
        if sel==0:
            
            
            conv=(len(str(sig1))-len(str(sig2)))*[0]
            for l in range (len(str(conv))):
                
                for i in range(len(str(sig2))):
                    
                    conv[l] +=(sig1[l-i+len(str(sig2))]*sig2[i])
                conv[l]/=(len(str(sig2)))
                out.next=conv[l]
            #plt.plot(conv) 
            #plt.show()
                    
    return hdl_1
def convert_1(hdl):
    m=32
    sel=Signal(intbv(0)[1:])
    out=Signal(modbv(0)[m:])
    inc= sin_1( sel,out)
    inc.convert(hdl=hdl)

convert_1(hdl='Verilog')
convert_1(hdl='VHDL')

These functions are missing:
from mmm import sig_square,sig_triag

I had a short look at the code, but this is far away from being ‘convertible’ at all.
