Get timing report from timing team. Surprise to see DC uses high delay cells which make the path failing the constraint by quite a bit. DC can easily use low delay cells to fix it. STA tool can fix it anyway. What really concerns me here is if DC takes…[Read more]
#dft difference of #Synchronous #reset and async reset
Sync abd async reset have their pros and cons. Rtl point of view, one signal can be connected to both async reset and sync reset. This is not true for dft. You will see async reset has one extra dft mux on the sync reset to add in dft…[Read more]
Check your clock constraints if so. Most cases it is not rtl issue. FFs are connected to a clock. But this clock is not defined in clock constraints. Synthesis and STA treat it as no clock since no clock information is available.
The idea is to send data from pc to fpga and then from fpga to spi flash. Pc to fpga communication can be done with uart. Fpga then implements an spi master module which converts uart data to spi data sent to flash from spi master module.
LWA (LTE/WLAN Aggregation) is a tight integration at radio level which allows for real-time channel and load aware radio resource management across #WLAN and #LTE to provide significant user perceived throughput (UPT) improvement. When enabling…[Read more]
#qualcomm ceo and others get low reelection vote and plan cost cut
Mollenkopf told investors following the company’s rejection of Broadcom’s bid that he could achieve earnings per share of $6.75 to $7.50 in fiscal 2019, through a number of measures, including a $1-billion cost red…[Read more]
Modelsim and vcs support using -y to specify source file folders. You can use -v to list all the verilog files you want to compile. But here is an issue. If some of your tests dont need some files, you may want to remove these files from file list otherwise…[Read more]
Another round of layoff just anounced. Surprise to most of us since product sells well. Senior and higher ranking guys are cut off more this time. Trim cost down and make room for youngers.
Now everyone is careful about their positions. Unwilling to share to make it harder to replace them.

A new Compute Through Power Loss (CPTL) tool suite and library developed at Texas Instruments’ Kilby Labs enables the use of checkpointing on limited resource 16-bit MCUs. When an MCU’s ope…[Read more]
Successfully used vivado HLS to synthesize cpp project into hw ip and havve it running on xilinx fpga. Note i said hw ip instead of rtl because generated rtl calls other xilinx cores which may further use other ips. There is NO file list to locate all the rtl…[Read more]
Read some ref. HLS generated rtl tends to be larger in terms of combinational logics, LUT, used. Usage of FFs, Mem, and ip core like dsp for multiply are similar. 50% to 100% higher. #HLS rtl also tends to do slower. I dont have manual crafted rtl to compare. This is…[Read more]
I have a modem module designed in matlab. Trying to port and test it on fpga these days. First generate c out of Matlab, then use ap fixed signal type to do floating to fixed point conversion. This usage of ap variable type is also required by Xilinx Vivado #HLS. Run sim…[Read more]
First #NB-IoT certification is announced in MWC 2018

Using modular arithmetic to avoid timing overflow problems
The short version: Given a starting time start, an ending time end and an interval interval, the way to check whether the interval has elapsed is to use the expression end – start >= interval. The naive expression end >= start +…[Read more]
