@Antaryami Panigrahi the error is the width (W=...) of
XM7
,
W=7u
. Sky130 has a 1e-6 scaling so the correct dimension is
W=7
a
Thanks @Stefan Schippers for reporting the error. But even after changing 7u to 7 also I am still facing the same issue.

@Antaryami Panigrahi please post the
Jaga_LDO_AEU_tb1.spice
file after the correction and the exact ngspice error. In my copy of this file after changing
M7
W
to
7
ngspice loads and simulates the file , it complains about non existent
Vout
in the plot command. This is correct since the
Jaga_LDO_AEU
subcircuit
Vdd
is hooked up upstream to
net1
, so the correct plot instruction is
plot v(net1)

Hi @Stefan Schippers, I have edited Vout to out in the plot command. But the error is still coming as attached in the image file. Thank you

@Antaryami Panigrahi I took your
Jaga_LDO_VC_LY_tb1.spice
, changed only the path of the
.lib
line and ngspice simulated with no problem. Check simulator version.

@Stefan Schippers I have updated it now to ngspice 43. But i am still stuck at the same error. Your video shows ngspice 43+, may i get the link?

@Antaryami Panigrahi Your ngspice is fine. My 43+ version is slightly newer than yours (I am using a development version from pre-master-44 branch of github ngspice repo), but this is not the reason for the failure. I see you have correctly set the .spiceinit file. I see the above spice file you sent was
Jaga_LDO_VC_LY_tb1.spice
while in image above I see
Jaga_LDO_AEU_tb1.spice
. please send the second one.
