Title: Assura RCX Problem Post by suederb on Sep 12th, 2006, 1:58am Hi, I have problem in doing Assura RC extraction. When I finished layout and did the RC extraction, I found there was a large capacitance between input and output. I thought that it might be some misunderstanding in setting the environment. the schematic and layout are shown below. Is there somebody can help me the solve the problem? thanks~ Netlist .GLOBAL AVDD AGND * .SUBCKT sch_trig IN OUT * * * caps2d version: 9 * * * TRANSISTOR CARDS * * MN1 net050 OUT AVDD AGND nch L=0.18U W=0.6U + AD=0.204P AS=0.204P PD=1.88U PS=1.88U + sb=3.4e-07 sa=3.4e-07 nrs=0.566667 nrd=0.566667 model="nch" fw=6e-07 MN0 net050 IN AGND AGND nch L=1U W=0.3U + AD=0.102P AS=0.102P PD=1.28U PS=1.28U + sb=3.4e-07 sa=3.4e-07 nrs=1.13333 nrd=1.13333 model="nch" fw=3e-07 MN16 OUT IN net050 AGND nch L=0.5U W=5U + AD=1.7P AS=1.7P PD=10.68U PS=10.68U + sb=3.4e-07 sa=3.4e-07 nrs=0.068 nrd=0.068 model="nch" fw=5e-06 MP0 net043 IN AVDD AVDD pch L=1U W=0.3U + AD=0.102P AS=0.102P PD=1.28U PS=1.28U + sb=3.4e-07 sa=3.4e-07 nrs=1.13333 nrd=1.13333 model="pch" fw=3e-07 MP1 AGND OUT net043 AVDD pch L=0.18U W=0.75U + AD=0.255P AS=0.255P PD=2.18U PS=2.18U + sb=3.4e-07 sa=3.4e-07 nrs=0.453333 nrd=0.453333 model="pch" fw=7.5e-07 MP13 OUT IN net043 AVDD pch L=0.5U W=3.5U + AD=1.19P AS=1.19P PD=7.68U PS=7.68U + sb=3.4e-07 sa=3.4e-07 nrs=0.0971429 nrd=0.0971429 model="pch" fw=3.5e-06 * * * CAPACITOR CARDS * * C1 IN AVDD 2.352E-16 C2 OUT AVDD 2.334E-16 C3 net050 AVDD 4.504E-17 C4 net043 AVDD 1.131E-16 C5 IN OUT 1.505E-01 C6 IN net050 2.334E-16 C7 IN net043 2.015E-16 C8 OUT net050 3.280E-16 C9 OUT net043 2.733E-16 C10 AVDD AGND 1.804E-15 C11 IN AGND 5.417E-16 C12 OUT AGND 5.026E-16 C13 net050 AGND 1.235E-16 C14 net043 AGND 5.323E-17 * * .ENDS sch_trig * |
