Hi,

I hope you are doing well.

I have designed and simulated a PA system in Cadence using high-level blocks, which include both ideal components and some defined with Verilog-A. My goal is to calculate the Bit Error Rate (BER) and Error Vector Magnitude (EVM) in the system. I am using an LTE source from RFLib, and everything functions correctly in the transient simulation.

To calculate these parameters, I intended to use envelope simulation. However, when I attempt to run the envelope simulation, I encounter convergence errors, which prevent it from working as expected.

Given this issue, I believe I need to work with transient data instead. Could you please advise on how to approach this in Cadence without exporting the data to MATLAB?

Thank you for your assistance.

Hello,

I am trying to design an RF mixer for a TX.
Assume my input IF signal is at 1 GHz, my LO at 2 GHz and I want my RF at 3 GHz, and assume that the mixer fully works after testing it with HB.
How to simply set the envelope analysis to check the EVM ?
I read through the documentation but I couldn't get it (I couldn't fully understand the settings of the source, probe, analysis.)
Which source and probe to use? I want custom modulation with custom bandwidth and center frequency.
Is there some examples for the ENVLP analysis ?

I am using IC23.1 and spectre 20.1.354.

The 'glamourless' north east Parliamentary constituency saw a lot of drama on voting day since morning. Comprising six assembly constituencies, it saw 55.35 per cent voter turnout. In 2014 the constituency had registered a 51.70 per cent turnout. Of this Ghatkopar east topped the list with 60.30 per cent followed by Mulund at 60.10 per cent, Vikhroli at 59.03 per cent, Bhandup west at 57 per cent, Ghatkopar west at 53.81 per cent and Mankhurd Shivaji Nagar at 44.02 per cent.

'Polling centre goes missing'

The day started with voters at Bhandup east complaining of an entire polling centre gone missing and alleged that it had been shifted two km away without prior notice. Citizens said they realised it only after reaching the spot and did not know what to do.

Bhandup resident Chandra Sreenivasan alleged that it was a ploy to discourage voters. "I wanted to vote. I fought with the election officer on duty and said that such tricks would not put off voters if they intended to do that. We have been voting at the same BMC garden every time and this time when we got the election slip, it had the same address but when we reached the spot, there was nothing there. A few locals then told us that it had been shifted near the old Bhandup phatak which is about 2 km away from the location," she told mid-day.

"The old and ill will not travel 2 km to an unknown spot, but I did not give up. I took an auto and went all the way there and fired the election staff on duty. When I questioned them, they said that they had just received a message in the morning to report here," she added. Election officials, however, said that it was decided to shift the polling centre from the garden to a building and a notice had been put up in the garden, though Sreenivasan said there were no notices.

Candidate posters put up

The BJP's secretary Vivekanand Gupta said they had reported a complaint against the NCP candidate after they found a banner with his photograph within 100 metres of the polling booth in Bhandup. He requested the EC to direct police officials to remove it immediately.

Faulty EVMs

Several complaints of faulty Electronic Voting Machines (EVMs) came to the fore during voting throughout the day, delaying the processes from 45 minutes to one hour. At some centres, there were issues with the Voter Verified Paper Audit Trail (VVPAT) slip as it was not visible after voting and in some cases there was an error displayed. At booth 93 at Sharon English School in Mulund the voting had to stopped after the EVM developed a snag and an engineer had to be summoned to fix it. Voting restarted after 45 minutes.

Candidate's switch disabled

An independent candidate, Anil Hebbar said his name was disabled on EVMs, and after his complaint the machines were replaced. "At booth 155/272 in Mulund, button no 14 next to my name was disabled. The officer in-charge discovered it before polling started and changed the ballot unit leading to a delay of 1 hr and 15 min," he said.

Voted, but not inked

A voter, Reena Verghese, alleged that she cast her vote in booth 243 at St Pius School in Mulund west, but her finger was not inked. She went again inside the booth to get the mark on her finger when she realised this.

Sr citizen's name missing

Kalawati Tambe, 86, missed out on voting as her name was missing from the electoral list. A resident of Kannamwar Nagar building 14, all her neighbours' names were on the list but her's did not figure. She said she came to vote though she was in her hometown for past few days. She complained that she had to climb onto the first floor, her legs were paining and she was very unhappy that she could not vote.

Jugaad chairs

At many places the election commission had put up jugaad chairs tied to sticks like a palkhi to carry senior citizens to upper floors in buildings where there were no lifts. "They showed videos of all those fancy automatic chairs, but they assembled such jugaad plastic chairs," Harkishan Rai, a senior citizen said. The rule of not allowing mobile phones was also leniently followed with cops telling voters that they could carry phones, but requested them to switch them off.
