Jaga_LDO_AEU.spice

@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

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.
