Formula One could race at circuits not on the current calendar as it seeks to rev up a 2020 season stalled by the coronavirus pandemic and against a backdrop of plunging revenues.

Six organizations that aid survivors of domestic violence are among groups that will receive $50,000 each from Major League Baseball and the players' association as part of a Healthy Relationships Community Grant initiative.

Experts are trying to figure out why the coronavirus is so capricious. The answers could determine how to best protect ourselves and how long we have to.

Over ten years ago, Suzanne Vega hit a terribly sexy groove with an album called Nine Objects of Desire that made me seek out every CD she has done since then. She’s kept us waiting for six years for her new studio effort, but it’s such vintage Vega that the reward is well worth the wait.

The first thing to note on Beauty & Crime is that producer Jimmy Hogarth and mixer Tchad Blake  have tuned the album’s tracks entirely to suit Vega’s rather inflexible, breathy voice. With the sonic help, Vega is freed up to focus on enunciating the layers behind her lyrics. Yet Hogarth and Blake also manage to seed each song with finely crafted arrangements and subtle hooks that make them musically interesting.

Although Vega uses a large canvas to record her ruminations, her most touching songs are those that are personal. On “Ludlow Street” she quietly mourns the passing of her brother: “I find each stoop and doorway’s incomplete/without you there”.

On the superbly produced “Bound”, she seems to be confirming her longtime friend Paul Mills’s continuing interest in her after her divorce from Michael Froom in 2001. On “As You Are Now” she manages – against all odds - to fit in a parent’s love for her child in four sweet verses.

Hi,

Is it possible to use a SystemVerilog package which is compiled into a library and then use it in a VHDL-2008 design file? Is such mixed-language flow supported?

I'm considering the latest versions of Incisive / Xcelium available today (Oct 2019).

Thank you,

Michal

I'm trying to generate IBIS models for the parts that I'm designing.  I'm designing using CADENCE Virtuoso.  

I'm wondering if there is a tutorial for generating IBIS models in CADENCE Virtuoso.   Please pardon me if my question is broad.      

Hello, i have a realy mistick thing going with copying libraries in cadence virtuoso,

When i copy straight forwart the whole library it gives me a warning that accsess was denied,but when i go into the library and copy it as a single file, then it goes fine.

another problem is it doesnt show in the massage console  ALL the files which could not be copied.(which is the much bigger problem,becuase i would have to pass threw all the subdirectories to verify if all files are there)

Is there a way to see which files wasnt able to be copied?

Thanks. 

Hello , i am trying to extract netlist from a circuit  in assembler

I have found the manual shown bellow , however there is no such option in tools in assembler.

how do i view the NETLIST of this circuit?

Thanks.

ASSEMBLER VIEW menu

Hello, I have a problem with a certain type of transistor,my hyrarchy has a lot components an sub components and visually inspecting them is very hard.

is there a way like in other cadence layout viewer tools , to enter the name of the component or a NET somewhere and it will focus on it visualy or give the hyrarchy path to it?

Thanks.

Hello, i am trying to produce a gain circles on a simple transistor as shown bellow.

i have defined the range from 1 til 30 dB and i dont get any circle just dots in infinity?

Where did i go wrong?
Thanks.

Hello, i have built a matching network of 13dB gain and  NF as shown bellow step by step.(including all the plots and matlab )

its just not working at all,i am doing it exacly by the thoery

taking a point inside the circle-> converting its gamma to Z_source->converting gamma_s into gamma_L with the formulla bellow as shown in the matlab->converting the gamma_L into Z_L-> building the matching network for conjugate of Z_L and Z_c.Its just not working.

where did i got  wrong?

Thanks.

gamma_s=75.8966*exp(deg2rad(280.88)*i);
z_s=gamma2z(gamma_s,50);
s11=0.99875-0.03202*i
s12=721.33*10^(-6)+8.622*10^(-3)*i
s21=-188.37*10^(-3)+30.611*10^(-3)*i
s22=875.51*10^(-3)-100.72*10^(-3)*i
gamma_L=conj((s22+(s12*s21*gamma_s)/(1-s11*gamma_s)))
z_L=gamma2z(gamma_L,50)

Hello, There is a manual in matlab of matching LNA  shown in the link bellow.

In it as shown in the plot bellow they mention input and output circle plots.

Is there such option of input and output circle in cadence virtuoso?

Here are two screen capture of Before and After Autorouting my board. Padstacks have all been revised and corrected. The Capture Schematic is correct. All Footprints have been verified after Padstack revision. a new NETLIST generation have been done after some corrections made in Capture. I have imported the new Logic. I revised my Layout Cross Section as such: TOP, GND, VCC, BOTTOM. Both VCC and GND shapes have been assigned to their respective logical GND and VCC Nets (verified). Yet, I still have the Autorouter to systematically use extra vias to make GND and VCC connections to the VCC and GND planes. Where a simple utilisation of the part padstack inner layer would have been indicated. What Im I missing ?

Hello,

I have a question I want to create a cover that consists a sparse values, pre-computed (a list or define) for example l = {1; 4; 7; 9; 2048; 700} I'd like to cover that data a (uint(bits:16)) had those values, Any suggestion on how to achieve this, I'd prefer to stay away from macros, and avoid to write a lot of code

struct inst {

  data :uint(bits:16);
  opcode :uint(bits:16);
  !valid_data : list of uint(bits:16) = {0; 12; 10; 700; 890; 293;};
  event data_e;
  event opcode_e;

  cover data_e is {
     item data using radix = HEX, ranges = {
     //I dont want to write all of this
     range([0], "My range1");
     range([10], "My range2");
     //... many values in between
    range([700], "My rangen");
    };

    item opcode;

   cross data, opcode;
};

post_generate() is also {
    emit data_e;
};
};

Hi all,

Is there any tutorial which explains the process of plotting the ISF function for a certain oscillator ?

Thank you.

Hello,

I am trying to import multiple verilog modules defined in a single file with "`define" directive in the top using Verilog In. The code below is an example of what my file contains.

When I use the settings below to import the modules into a library, it imports it correctly but completely ignores all `define directive; hence when I simulate using any of the modules below the simulator errors out requesting these variables.

My question: Is there a way to make Verilog In consider `define directives in every module cell created?

I am using the following Cadence versions:

MMSIM Version: 13.1.1.660.isr18

irun Version: 14.10-s039

Spectre Version: 18.1.0.421.isr9

Hello,

I am using Virtuoso 6.1.7.

I am performing the parasitic extraction of a MOM cap array of 32 caps. I use Quantus QRC and I enable field solver. I select “QRCFS” for field solver type and “High” for field solver accuracy. The unit MOM cap is horizontally and vertically symmetric. The array looks like the sketch below and there are no other structures except the unit caps:

Rationally speaking, the capacitance values of the unit caps should be symmetric with respect to a vertical symmetry axis that is between cap16 and cap17 (shown with dashed red line). For example,

the capacitance of cap1 should be equal to the capacitance of cap32

the capacitance of cap2 should be equal to the capacitance of cap31

etc. as there are no other structures around the caps that might create some asymmetry.

Nevertheless, what I observe is the following after the parasitic extraction:

As it can be seen, the result is not symmetric contrary to what is expected. I should also add that I do not observe this when I perform parasitic extraction with no filed solver.

Why do I get this result? Is it an artifact resulting from the field solver tool (my conclusion was yes but still it must be verified)? If not, how can something like this happen?

Many thanks in advance.

Best regards,

Can
