check the cell_name and top level name in the gds and cdl should match. from the error it appears that GDS doesn't have the cell at all.... you can do strings it will give you the strings in the gds file....that should have the cdl top level subckt name.
Dear jimspring03. I have the same problem with the same technolgy (UMC 0.13um RFCMOS). All devices in schematic netlist (subckt statements missing, exactly as in your attached file) are not find in the netlist. Did you find the solution? See attached screen. Best regards, André. - - - Updated - - - My scree
HI Fellow engineering students. I have a question regarding to "lvs error" that I am having. Main problem is from using any device from umc13mmrf library that's using "PSUB" pin. I am saying this because any time I used the device that has "PSUB" pin just like I showed in the attachment(inductor in this case), when I go to the sourc
Hi - I have a problem. I want to use std cell components to simulate within my schematic using cadence 5 spectre. From the std lib I have a .spi and a .cdl file. Thus I am using the line simulator lang=spice at the top of the .spi file. In that file all std gates are defined as .subckt. I have an example schematic with 2 inverters.
Hello EDA fellows, Please help me on how to implement a nested/hierarchical subcircuit on the source netlist in the cadence LVS check. My source netlist goes like this; .subckt name1 param1 param2 .subckt name2 param3 param4 ** content*** .ends .subckt name3 param5 param6 **content*** (...)
I'm late but couple remarks anyway: As said above the problem could be in the pin order of subckt definition/call. - if you are using cadence schematic view to the netlist extraction for Calibre you should be so careful with the subcircuits CDF properties like pin order. Try to check if this property is the same in the CDF and symbol. Otherwise i
Check your netlist file. Most of the times, there are only .subckt definitions there. You will have to instantiate the top-level of your design in the netlist. That's all I can think of...
In Hspice, a sub circuit can be defined for an inverter and a scale parameter could be defined like this .subckt inv in out k=1 xmp out in vdd vdd pfet w='2*k*140n' l=90n xmn out in gnd gnd nfet w='k*120n' l=90n .ends Later, this inverter can be called by using x1 vin vout inv k=4 here k=
Hi, I use 4 depending current sources in a subckt. The voltage should be depending on the current which flows through one of the others. I decided to use ccvs sources. How can I configure such a source to work like I want. What is the port parameter? How can I set the dependency? Thx.
Hi I am trying to import cdl to schematic in cadence. I did get the schematic, but whenever the cell has more than 1 output, only one output is correctly converted, all other outputs are converted to inputs. For example, the following cdl netlist: .subckt ADDFHX1 CO S A B CI M0 net105 net123 net132 VDD P l=0.18u w=0.72u M1 net105 net117

Hi, I like to run montecarlo analysis in cadence 5.1 version. I have the follwing files for running a monte carlo analysis on a resistor: simulator lang=spectre parameters monteres=1000 inline subckt model (monteres PLUS MINUS) parameters monteres_dev=monteres model ( monte_res PLUS MINUS) resistor monte_res = monteres_dev ahdl_incl
I use hspiceD simulator for generating hspice netlist( IC5141 ). My netlist has a big problem in subckt definition. I want like below ----------------------------------------------------------------------------------- .subckt inv_p a y inh_vdd inh_vss pw=default_value nw=default_value ----------------------------------------------
Hello, I am having a resistor SPICE script that is provided by a manufacturer. The SPICE script begins with .subckt keyword. My question is how can I create my own resistor in cadence Schematics so that the resistor that I create can reference to that resistor SPICE script. I would appreciate your help if anyone of you can provide me some brief
I would like to add the resistor with the following hspice code into my library in cadence. Is there any good way to add it? .subckt rlrrf plus minus psub w=2e-6 l=10e-6 strips=1 .param cterm = 0.1013e-3 .param lterm = 0.84e-6 .param rterm = 29.39 .param width = w .param ns = strips .param length = 'l/ns' .param dw = 0
Hi, I'm trying to simulate a basic SRAM cell 6T with cadence Spectre simulator and Ocean script. More precisely, I need to carry out a parametric analysis but I haven't succeeded in. Here's my netlist : ///////////////////////////// // basic gates description // ///////////////////////////// subckt sramCell WL BLb BL M0 net0
Dear Sir: when I use CDL out to export netlist from cadence composor to HSPICE... there is a line of "*.PININFO..." like: .subckt sc_res_P2_2d34P A1 A3 CK<1> CK<2> CK<3> CK<4> CK<5> CK<6> CK<7> CK<8> +VAG VDD VSS *.PININFO A1:B A3:B CK<1>:B CK<2>:B CK<3>:B CK<4>:B CK<5>:B CK<6>:B CK<7>:B +CK<8>:B VAG:B VDD:B VSS:B MM0 net054 net
cadence composer will generate netlist based on schematic you draw. However, sometimes, I need the composer to generate netlist which can not be represented by any of its components, such as w-element for hspice. Can I customize a symbol and its content, so that I can put what I want in that customized component, then composer will generate n
