**BUG** Concise problem statement: Running a TL081EE simulation with a pasted-in edited copy of the TL081EE subckt is broken. Pasting in and editing a copy of the TL081EE and other in-house opamp or comparator subckts used to work. Please see: https://easyeda.com/editor#id=B42omkh1n Steps to reproduce the problem. 1) Draw a schematic with the 5 pin Opamp and change the part name to TL081EE; 2) Copy the subckt for the TL081EE from the netlist for this schematic; 3) Paste it into this schematic; 4) Change the name of the subckt to make it different from TL081EE; 5) Paste in a copy of the LM108 netlist from: https://easyeda.com/example/LM108_using_a_pasted_in_subckt-afLFztL3X and set it to "spice"; 6) With the pasted-in TL081EE_edited subckt set as "comment", do: Ctrl+R then select "Transient" then click "Run" to run a time domain simulation. The sim runs OK. 7) With the pasted-in TL081EE_edited subckt netlist on the right set as "spice", do: Ctrl+R then select "Transient" then click "Run" to run a time domain simulation. The sim does not run and the simulation results window shows: *********************************************************** Circuit: untitled Doing analysis at TEMP = 27.000000 and TNOM = 27.000000 doAnalyses: out of memory tran simulation(s) aborted ngspice-26 done *********************************************************** Doing: Super Menu > Miscellaneous > Netlist for Document > Spice... shows and empty netlist: *********************************************************** New Schematic .param pi = 3.141593 .func LIMIT(x, y, z) {min(max(x, min(y, z)), max(z, y))} .func PWR(x,a) {(MAX(ABS(x), 1e-313))**a} .func PWRS(x,a) {sgn(x) * PWR(x,a)} .func stp(x) {u(x)} .func log10(x) {ln(x)/ln(10)} .func SQRT(x) {(MAX(x, 1e-313))**0.5} .func INT(x) {sgn(x)*floor(ABS(x))} .func URAMP(x) {max(x,0)} .func POW(x,a) + {(((a-(int(a)))==0)||(sgn(x)>=0))*( max(exp(ln(uramp(x))*a),0) + + (2*(0.5-ABS((int(a))-2*int(a/2))))*max(exp(ln(uramp(-1*x))*a),0) )} .control quit .endc .END *********************************************************** The LM108 netlist shows that this is not a general problem with all pasted-in subckts. The problem seems to be something to do with the copied and pasted version of the TL081EE subckt. * Pasting in and editing a copy of the TL081EE and other in-house opamp or comparator subckts used to work. Has there been a change to the way some character or string in the schematic editor that now breaks schematic parsing of the pasted in netlist?
