Branch : quicklogic : Dump report file for the area utilization

[kkumar23]

uart.zip

Is there any option to dump the summary of the area utilization , as shown below:

---

Device Utilization for QLAL4S3/PU90

---

Resource Used Avail Utilization

IOs 17 32 53.13% LCs 28 891 3.14% DFFs 47 891 5.27% ClockCells 2 5 40.00% RAM8Ks 0 8 0.00%

If not, supported can be provided ?

Yosys does not really have info about available resources. That kind of report should rather be generated in VPR.

Thank you for the quick reply. What is the option to dump the console log ?

when you run the build the flow should write the logs from each stage into files. So in the pack.log file you can find:

Pb types usage...
  PB-SYN_VCC   : 1
  PB-SYN_GND   : 1
  outpad       : 4
  VCC          : 1
  INPUT        : 1
  bidir_buf    : 5
  OUTPUT       : 4
  inpad        : 1
  BIDIR        : 5
  LOGIC        : 38
  PB-LOGIC     : 38
  f_frag       : 1
  GND          : 1
  q_frag       : 24
  c_frag       : 38
  PB-SYN_IO    : 5
    EMPTY: # blocks: 0, average # input + clock pins used: 0, average # output pins used: 0
    PB-LOGIC: # blocks: 38, average # input + clock pins used: 16.8684, average # output pins used: 1.65789
    PB-ASSP: # blocks: 0, average # input + clock pins used: 0, average # output pins used: 0
    PB-SYN_IO: # blocks: 5, average # input + clock pins used: 2.8, average # output pins used: 0.2
    PB-SYN_VCC: # blocks: 1, average # input + clock pins used: 0, average # output pins used: 1
    PB-SYN_GND: # blocks: 1, average # input + clock pins used: 0, average # output pins used: 1
Absorbed logical nets 5 out of 71 nets, 66 nets not absorbed.
FPGA sized to 35 x 33 (ql-eos-s3)
Device Utilization: 0.04 (target 1.00)
    Block Utilization: 0.04 Type: PB-LOGIC
    Block Utilization: 0.16 Type: PB-SYN_IO
    Block Utilization: 1.00 Type: PB-SYN_VCC
    Block Utilization: 1.00 Type: PB-SYN_GND

The above example is for a simple 24 bit counter design. The Pb types usage ... counts usage of every block type used in the device. The Device Utilization section sums that up.
